Cynopotamus atratoensis

6. July 2007

Only three of these predatory characins found their way to Aquarium Glaser. This group of characins form the subfamily Cynopotaminae within the family of real American characins (Characidae). The representatives of this subfamily are relatively large fish, which can reach a total length between 15 and 30 cm in adulthood. Cynopotamus have large mouth openings with strong jaws obtaining long needle sharp teeth. This makes it possible to chase even large fish by having a strong grip on their large and strong prey. Cynopotamus can be found throughout subtropical and tropical South America. They mostly live in clear and white water habitats. These are territorial characins. Unfortunately these fish are not imported regularly to Europe and observations in captivity of these fascinating objects can therefore rarely be made.(Photo: Frank Schäfer, Text: Izaak den Daas)

Rineloricaria melini

6. July 2007

As a further german bred rarity we can offer Rineloricaria melini at present. Our specimen of the probably most attractive Rineloricaria species have with 9 – 12 cm length already attained full growth and are of outstanding quality. Their origin is the area of the Rio Negro where they live in black water biotopes. Like all Rineloricaria species they are cave spawners in the male gender. An aquarium for Rineloricarias should have densely planted zones, and also open areas and some caves. They are omnivores, which need both vegetable and animal food.

Chromobotia macracanthus

6. July 2007

In our picture you see an interesting mutant of the clown loach, which reached us these days. Although Chromobotia macracanthus formerly known as Botia macracantha is a long time tank inhabitant, it is still not without mysteries. This applies particularly to the breed, so far we have only coincidence success. Also in the maintenance they can make problems, since they are very susceptible to stress. Catching and transfer should take place only in absolutely necessary situations, because they are particularly prone to whitespot disease (Ichthyophthirius multifiliis) when stressed in any way. When well acclimatized clown loaches are beautiful and interesting fishes. A certain behavior can surprise the inexperienced owner. Sometimes they lie on their side when resting – which may alarm those not familiar with it, as the fish may appear to be ill! They may also make audible clicking sounds, particularly at feeding time. They tend to be more active if kept as a small group, rather than singly or in pairs. Further there should be a lot of hiding places in the aquarium to keep the stress for the animals as small as possible.(Photo F. Schäfer, Text K. Diehl)

Hypancistrus zebra L 46 „Double Tailfin

6. July 2007

November 2006: At present we can offer beside „normal “German bred zebras (surely the most demanded of all L-numbers) an individual with a doubled lower caudal fin. This change of the fin is probably to be led back on a disturbance in the embryonic development. If someone hopes to breed a race of „veil tailed zebras “ with this fish, it will probably end in a disappointment. Nevertheless: absolutely unusual, a rarity amongst the L-numbers.

Eretmodus cyanostictus „Kigoma“

6. July 2007

Eretmodus cyanostictus is among the group of cichlids called gobies. Gobies only occur naturally in the surge habitat of Lake Tanganjika, which is the upper meter of the water at the shoreline. They unique in that their swim bladder is non-functional, meaning that when they’re not swimming, they drop to the bottom like a rock. E. cyanostictus is an algae-scraping cichlid that has a uniquely interesting spawning behavior – it’s a bi-parental mouthbrooder. Gobies are best kept as pairs. It’s possible to keep more than one pair in the same tank, but realize they can be quite pugnacious to one another. A single pair can be kept in a tank as small as 40 gallons, but two pairs should be housed in a tank no smaller than 75 gallons. Gobies in general can be quite nasty to each other, but once pairs form, “the fight is over.” Males and females will form a pair-bond that lasts for life. The food of choice for E. cyanostictus is a good Spirulina flake. Mysis and Cyclops make good supplementary foods. Suitable tankmates include other algae-eating tanganyikans, such as Tropheus and Simnochromis species.

Gercarcinus ruricola

6. July 2007

This splendid land crab (Halloween-Crab, Gercarcinus ruricola) occurs in two colour variants, specifically with red or white base coloration. The colour variation involves both sexes. A mixed pair lived together in harmony for several weeks in my terrarium. These creatures are essentially vegetarian, but will occasionally take frozen foods intended for aquarium fishes, eg bloodworm. They are particularly comical to watch when they gnaw the stem of parsley which looks like theyíd hold bretzel sticks. Even though these crabs remain on land for most of the time, a shallow dish containing regularly changed water should be placed in the terrarium for them. These crabs are crepuscular, preferring to remain in hiding during the day. Even if they appear to be very peaceful among themselves, it must always be borne in mind that crabs (like all crustaceans) are soft and vulnerable after moulting. Hence newly-moulted specimens require secure hiding-places in order to be safe from the very real danger of cannibalism by their companions. These creatures are exceptional climbers, so the container must be tightly covered! Planting the container is problematical on account of the feeding habits of the crabs. Be especially careful to avoid poisonous houseplants!(Photo F. Schäfer, Text K. Diehl)

January 2006: For the first time in Germany: The fiddler crab Uca ornata. We are proud to introduce this new species to the pet market. We got only few animals from Ecuador, hope however for further imports of this species. Further information for the maintenance of this at the Pacific coast from Ecuador to Nicaragua spread species are naturally not present at this time, however it will probably not differ substantially from the other fiddler crabs . The aquarium should have a large land part on that fiddler crabs preferentially stay, besides that a water part with shallow water is needed.

With them as with many swarm fish the effect on the observer rises with the swarm size, a group of 30 animals is always impressing. Glowlight danios are good to keep and also to breed in a neutral, middle-hard water. On the nutrition they do not have special demands, with commercial flake food they are sufficiently supplied, however a certain alternation should also be granted to them. Due to their small size they can be already maintained in aquaria starting from 60cm length. Without any problems they can be socialized with other fish and represent a beautiful alternative to the Zebra Danio. (Photo F. Schäfer, Text K. Diehl)

Labeo barbatus

6. July 2007

As a further new import from the Congo we can present you Labeo barbatus. It is a about 60 cm growing representative of the genus Labeo, which is represented in the Congo River with at least 34 species. In its habitat it lives in sections with strongly flowing waters. About its behaviour in aquaria little is known, thus here one enters new ground. Since Labeos generally become more aggressive with increasing age, a good structure of the aquarium is meaningful. Thus territory borders have to be offered and retreat areas for suppressed individuals to be created. For this purpose bogwood, stones, bamboo, plants etc. are suitable. Against food and water chemistry they usually place no high requirements, they must be naturally sufficiently fed and the water filtered accordingly. Fishes of this size and vivacity need very roomy aquariums and do not belong not into the hands of beginners.(Photo F. Schäfer, Text K. Diehl)

Nhamunda Rosé is the trade name of a strain of the brown discus Symphysodon aequifasciatus axelrodi originated in the Rio Nhamunda (northern influent of Amazon, west the city Alenquer). Now again some Nhamunda Rosé are available. Characteristic for this variety is the partially laminar high red part of the brown primary colour. Thus they are not only for fans of true bred location variants but also for breeders of new colour forms from interest. Their maintenance requirements are typical discus like: soft water, high temperatures, good hygienic conditions as well as a balanced nutrition. Best one maintains it in a group of at least 6 animals and avoids a developing of social stress, since this is probably decisive for the occurrence of the most diseases in discus keeping.(Photo F.

Pristobrycon maculipinnis

April 2006: This week we got some very nice Pristobrycon maculipinnis. This rarely traded and in the fish keeping hobby almost unknown species is characterised by intensive red colored fins, as well as a pronounced examination of black markings over the silver shining body. Maybe it is the most attractive of all Piranhas, it originates from south Venezuela where it inhabits black water biotopes. There they feed on fruits and seeds that fall onto the water, as well as of fish and their fins. This is to be considered during their maintenance in aquaria, at the best they should be kept solitary. A careful socialisation with conspecifics or other large species might be possible. In some zoological gardens you can see groups of Pygocentrus (Serrasalmus) nattereri that have been kept together there for several years. Since all Piranhas react very sensitively to stress all uneccesary handling in or near the tank should be avoided. (Photo F. Schäfer, Text K. Diehl

Rineloricaria sp. „Colombia“

6. July 2007

A remarkable species which came in in one of our import from Colombia. These fishes also originate from the Rio Chacu in the northern tip of the country. Because of the many bristles of the male this species has been falsely determined as Rineloricaria latirostris. A comparison with the pictures (see Mergus Catfish Atlas Part I) of the different species shows clearly the distinction, and will leave no room for doubts. This species is not demanding in the home aquarium and is breeding willingly when offered caves in the form of tubes. This is a productive fish and can easily lay 100 and even more eggs. The striking bristles on the head of the male are completely missing on the female. Also the basic colouration of the female is more lighter. The final length is approximately 18 cm.

Glyptoperichthys joselimaianus L 1, L 22

6. July 2007

Glyptoperichthys joselimaianus the “White Spot – Glycopterichthys” originates from the Rio Araguaia, one of the main tributaries of the Rio Tocantins in Brazil. There it inhabits different habitats, it was found e.g. on deadwood and also on flooded meadows. Natural water conditions (white water) do not have to be copied for maintenance, L 1 are very adaptable fish. One condition for the maintenance of adult Glycopterichthys species is however the ownership of a very large aquarium. With an overall length of approximately 40 cm, which can be reached in aquaria too, they are really stately catfishes. It is very impressing to see such a fish sailing elegantly through the aquarium. Sail Fin Plecos are not shy compared with many other Loricariids. Their large appetite is noteworthy this requires a strong filtering unit. Wild caughts of this species are only rarely found in the trade, predominantly the offered animals are asiatic pond breeds.

Awaous cf. lateristriga

6. July 2007

From the coastal ranges of the western Africa between Senegal and Angola originates the freshwater goby Awaous lateristriga. The animal introduced here reminds strongly of this species, whether it is identical to it could yet not be determined. With an overall length of approx. 30 cm Awaous lateristriga belongs to the larger gobys. In their habitat they inhabit fresh water biotopes such as swamps, flooded fields and periodically draining rivers and also brackish water biotopes. Since they are imported only very rarely, nearly nothing is known about their maintenance in aquaria. Related species such as Awaous flavus are maintained occasionally in aquariums and also bred in some rare cases. With their maintenance and breeding a changing salinity of the water plays a crucial role. This corresponds to their life cycle, since the larvae are born in the fresh water, then drift passively in the sea or in estuaries, in order to ascend after some months again in the fresh water. There then the adults live and the reproduction cycle starts again.(Photo F. Schäfer, Text K. Diehl)

Betta falx, belonging to the Betta picta form circle, was scientifically described 1998 by Tan and Kottelat. Their origin is the central part of Sumatra, where it occurs in dense overgrown, nearly standing waters. The water conditions at the habitat (pH 5.7, GH 0 – 1, KH 0 – 1) do not have to be kept in the aquarium, Betta falx get along even with higher water equivalents. One can already maintain several pairs of those about 6 cm largely growing species in a 60 cm aquarium. The aquarium should be densly planted and not lighted up too strongly. A nutrition with small living food such as Cyclops, water fleas and Culex larvae is ideal, frosted- and flake food is however likewise accepted. Betta falx is a mouth breeder, the male takes care on the approximately 70 eggs, while the female takes over the territory defense. The raising of the fry with Artemia Naupliae is not difficult.(Photo F. Schäfer, Text K. Diehl)

Sphaerichthys vaillanti is probably the rarest and most desired species of the Chocolate Gouramies. Their origin is Kalimantan the indonesian part of Borneo. Since they are black water inhabitants, the water equivalents should be adapted in the aquarium to it. This species does best in peat filtered water. Water must be changed often, and a good water conditioner must be used. The tank should be heavily planted with a cover of floating plants. Use a filtration system that creates only slight circulation. Also regarding the nutrition they have increased requirements live food as brine shrimp, mosquito larvae and fruit flies will do best. Red mosquito larvae and Tubifex should be avoided because of the often unclear origin (possibly waste water). S. vaillanti are peaceful, timid fish that are best kept in a pair in a species tank. Although, if combined with other fish, keep with other small, calm, nonaggressive species. A demanding species, recommended only for expert aquariasts. The Chocolate Gourami is the most difficult Labyrinth fish to care for. (Photo F. Schäfer, Text K. Diehl)

Geophagus crassilabris

6. July 2007

Very large animals, up to 20 cm, came to us from Colombia. These beautiful fish came as well from the Rio Chacu. These eartheaters live in nature in a habitat of moderately flowing streams and rivers. Remarkably for this group of eartheaters is the way they breed their eggs, not as normally in the throat area, as known with most mouthbreeding cichlids, but in the oral cavity. With this type of mouthbreeding you can clearly see that the fish are spreading their operculum and need to expand their upper lip. The lips of G. crassilabris are clearly thicker then its two relatives, G. steindachneri and G. pellegrini. These fish should not be kept in pairs but as a group with one male and several females as known with many Malawi and Tanganyika cichlids. This mating system is called “open polygyny”. These eartheaters are easy to keep and eat all available fish food, including flakes and tablet food.(Text: I. den Daas, Photo: F. Schäfer)

This, by specialised hobbyists of large South American cichlid, well known species is only very rarely offered to the public. Our animals were imported from Columbia. The best way to take good care of these beautiful cichlids, which can grow up to 40 cm, is to keep them in large fish tanks with plenty of hiding places, which they need because of their high interspecific aggression. The optimal water should be warm (27 to 30 degrees Celsius), and preferably soft and acideous. The parrot cichlid is omnivorous in nature and therefore should be offered plenty of vegetable foods as well. Breeding has been reported on several occasions and is a real challenge for the experienced and dedicated fish-breeding hobbyist. This species is relatively sensitive to hole-in-the-head disease and therefore a good aquarium hygiene should have the highest priority.(Text: I. den Daas, Photo: F. Schäfer)

For the first time we can offer now both: very beautiful wild caught and German breds in an excellent quality. Because Tahuantinsuyoa macantzatza has already attained full growth with a length of maximally 12 cm, they are suitable for medium sized aquariums. They do not damage plants, can thus be accommodated in tanks, decorated with bogwood and plants. Their interesting brood care as larvophile mouth breeders (the eggs are set off and bred first on a substrate, then the larvae are protected in the mouth) permits interesting behaviour observations. In particular it is always exciting to observe the transfer of the fry between the parents. Towards feeding there are no special requirements posed, the water should be not to hard and exhibit a slightly sour tendency.(Photo Thomas Weidner, Text Klaus Diehl)

This by water and land affected biotope has to be reproduced in the terrarium, since they need both habitats for their well-being. With some bogwood and stones the land part can be arranged, as water part a simple, flat basin filled with brackish water is sufficient. Some hard plants can complete the decoration. A close not displaceable covering is necessary, particularly if the decoration reaches the edge of the aquarium, since crabs are protruding escapees. As omnivores they are to be nourished rather unproblematically. In water frosted food can be fed, on land vegetarian food should be handed.

Oryzias celebensis the Celebes rice fish originates, as the species name indicates, from Indonesia where it inhabits the island Celebes. It lives in standing to slowly flowing waters which are heavily planted. As an approximately 5 cm large becoming schooling fish it needs a free swimming area and retreat possibilities, since rice fish occasionally tend to become somewhat quarrelsome among themselves. With their maintenance it is to be considered that Oryzias celebensis prefers rather high pH values. Optimal water should exhibit a pH of 8 and also a not to small water hardness (DGH 10°). In such a water even the breeding of rice fish is possible. Interesting is that the female carries the eggs several hours before attaching them to a substrate. The raising of the fry should not be difficult.

Ancistomus sabaji – Hypostomus spec., Peckoltia spec.? A fish with many names! There is hardly another L number catfish where the confusion regarding the nomenclature is as large as with this species. This is a result of the generous allocation of numbers (L 75, L 124, L 301 and LDA 2) for this fish. One reason for this fact is the large area of origin where numerous deviating color forms exist. For the hobbyist this should be no real problem, since all varieties are attractive and can be easily kept. They can get larger than 20 cm and need therefore roomy aquariums. As expressed omnivors with only little aggression they are very well suitable for community tanks.

The information about the occurrence in brackish and seawater shown in older publications are probably based on a mistake, because there is a similar looking seawater puffer species (Ephippion guttiver) occuring in Cross-River. You will find more hints and useful information in AQUALOG (volume 16) The Puffers Of Fresh- And Brackish Water.(Photo Aquarium Glaser, Text Dr. K. Ebert)

Cherax lorentzi

6. July 2007

In its shining armour Cherax lorenzi reminds of a medieval knight, who is on its way to the tournament. With a size of 12 cm it can be kept very good in aquariums starting from 100 cm length. Contrary to some of its relatives Cherax lorenzi does not seem to harm other tank mates. Therefore it seems to be suitable also for community tanks. This would have to be well arranged and equipped with numerous caves and hiding places. Also a certain plant compatibility is certified to them, the vegetable portion of the food should be kept high. As omnivores they can be nourished with staple food (granulates/stick), this should however be supplemented by fish meat, Shrimps, frosted food as well as carrot, cucumber, Zucchini, salad and other vegetables. Towards the water chemistry no special requirements are placed, they have been bred already several times at 25°C. The youngsters have a very high oxygen demand, a good filtering, water movement and a good aeration should be thus present in the aquarium.(Photo F. Schäfer, Text K. Diehl)

Diskus „Wild Lago Inanum“

6. July 2007

This very beautiful discus fish is traded as well under the name „Semi Royal Blue“. Wild caught discus fish are just beautiful! It is remarkable that still new wild type varieties are found and imported. Wild caught discus fish will not be feeling themselves well if not kept under optimal conditions. This malcontent will be seen very fast by bad colouration and shy behaviour. If your wild caught discus fish is looking rather pale, something is definitely wrong with the aquarium conditions. But please do not became worried too fast if your discus fish is not optimally coloured, because colour intensity will become visible in time, even after several months of obtaining the fish from your trader followed by optimal care. The fish will become more and more beautiful week after week. The most important criteria for obtaining these fish is therefore not colouration but body form, size of the eyes, form of the fins and their natural behaviour. (Text: I. den Daas, Photo: F.

This pleco is a harmless solitude fish, very well suited for the cichlid aquarium. It is an animal who has a nocturnal way of life and will show most activity at dawn and dusk. During the day it will rest at a shadowy place under a stone or piece of bogwood. The representatives of the pleco species live in fast streaming rivers but also in flooded areas. They feed in the aquarium preferably on vegetarian food like salad and boiled pees or Brussels sprouts, but this fish is not picky at all and will eat all kind of flake or tablet food as well.(Text: I. den Daas, Photo: F.

Heterotis niloticus

6. July 2007

As next the relative of the largest truly freshwater fish Arapaima gigas Heterotis niloticus has a large attractiveness. With a maximum length of scarcely about one meter it is however more suitable for the aquarium maintenance than its South American relatives. In Africa they originally inhabit different waters types south the Sahara.

A difference to all the other bonytongues lies in the way they nourish. It feeds mostly on plankton, being the only plankton-feeder of the Osteoglossidae.

Live red mosquito larvae have proven to be the ideal food for this species of fish. Even 30-40 cm long specimens eat this food enthusiastically.

For our customers: depending on their size, the animals have the code numbers 140500 (3-4 cm) to 140507 (25-35 cm) on our stock list. Please note that we only supply the wholesale trade.

Enneacampus ansorgii

6. July 2007

The small freshwater pipefish originates from Western Africa, from Cameroon to Gabun and in the Zaire- and Ogowe River. These fish inhabit freshwater as well as brackish water habitats. Addition of sea salt (1-2 teaspoons per 10 litre of water) will therefore increase the vitality of these fish. This species, but actually all freshwater pipefish, need a special fish tank for its own in order to thrive because they are slow eating fish. They eat only life food like daphnia, cyclops, brine shrimps and the smallest fish fry. Breeding has been performed successfully in captivity on several occasions. The female lays her eggs over the breeding pouch of the male pipefish. The eggs are attached on the male animal behind the vent within an area bordered by 2 folds, which form the breeding pouch. These fish need regular water changes and a clean fish tank but will give their owner many pleasure by displaying beautiful colouration and an interesting behaviour.

At present we can offer this magnificent variant of Uaru amphiacanthoides originating from Santarem. The fish impress by their metallical resplendent body and the cherry red eyes. All Uarus are expressed plant lovers. Beside a meaty nutrition vegetarian food should be offered. The food spectrum is large, almost all fruit and vegetables are accepted and eaten greedy after habituation. This applies naturally also to aquatic plants, so that a Uaru aquarium looks usually quite bare. You can try to add to an with roots and stones decorated fish tank some “hard” aquatic plants e.g. Anubias or Microsorium species. Since they can reach with approximately 25 cm a stately size, large aquaria are needed (> 150 cm). Under to bright light Uarus do not feel particularly well. Since they have calm temper, they do not like a socialization with hectic tank mates.(Photo F. Schäfer, Text K. Diehl)

THE SPECIES HAS BEEN DESCRIBED SCIENTIFICALLY IN THE MEANTIME UNDER THE NAME OF BORARAS NAEVUS. PLEASE CHECK THE FOLLOWING PAGE: http://www.aquariumglaser.de/en/boraras-naevus_de_1397.html

This scientifically undescribed dwarf fish was imported from Singapore. They have very bright coloration and will not outgrow 1.5 cm in length. Like all Boraras dwarfs these fish need a special aquarium on their own. This species requires soft water, dens groups of fine leafed plants in the background and surface plants for dimmed light. Filtration with peat increases the colours of these fish. Because these fishes are so small large amounts of offspring cannot be expected. The best thing to do is breeding in a continuous way. Feeding should be done with the smallest food available, like cyclops, artemia fry or finely grated flake food. These fish prefer high temperatures between 25 and 28 degrees Celsius.

This species is the smallest representative of the carp family. It length does not exceed 1.5 cm. This fish comes from Myanmar (former Burma) and is imported only rarely. It is a typical shoaling fish and apparently lives in nature in large formations. Male fish attract the females for mating with clear croaking noises. These precious little fish need an aquarium of their own. Breeding is possible in an aquarium with large bushels of plants like Java moss, which give the fry a chance to hide and micro- organisms the opportunity to flourish so they can be used as the first food for the very small fry. But also the adult fish need small food particles, like newly hatched brine shrimps, small copepods and microworms. (Text: I. den Daas, Photo: F. Schäfer)

Labiobarbus leptocheila is a up to 30 cm long barb originating from Southeast Asia. There it is found from the Mekong area over the Malayan peninsula to Java, Sumatra and Borneo. Typically for the genus Labiobarbus is the protracted dorsal fin, as well as through black marks on the scales formed longitudinal stripes. In their habitat they inhabit midwater depths and the ground of larger rivers and streams. There they feed upon plankton. According to their size they need large aquaria, which should have some shelters and hiding places. Since they like plants, the aquarium should be planted only with hard specimen. A generously dimensioned filtering unit, as well as frequent water change should be normal with animals of this size. No information about successful breeding attempts is present to us.(Photo F.

Salminus brasiliensis (formerly: maxillosus)

6. July 2007

April 2004: At present Aquarium Glaser can offer Salminus brasiliensis (formerly: S. maxillosus) as a further characin rarity. This up to 1 m and over 20 kg growing fish is a migratory species. These migrations take place from October to January, and are correlated with the rise of the water levels as well as the rising length of day. They follow their prey at their migrations to their spawniong grounds. Both in migratory behavior and in appearance Salminus species reminds on the salmon species, and like them they are threatened by dams, barrags and the environmental pollution. As estimated food fish they are fish farmed in Brazil. At the maintenance in aquaria their rowdiness is to be considered, with their strong dentures they can hurt their tankmates, therefore even for young animals should large aquariums be available. Since they are strong devourers their appetite can not be satisfied with flake food in the long term. Sometimes a defrosted fish should be fed.(Photo F. Schäfer, Text K. Diehl

Until a few years ago Red Phantom tetra, Hyphessobrycon sweglesi was easy to identify, even though under the name of Megalamphodus sweglesi. Lately “Red Phantom Tetras” appear more often, which are very similar to it, but also show other characteristics. It stays (temporarily) unclear, if they are own species, subspecies or “local forms”. Interested hobbyists, who would like to breed this tetra should know that the young fish are very small and prone to “infusorios” and that they require smallest life food in the beginning , if possible. Their growth is extreme slow during the first weeks/months. For this reason wildcaught ones are prevailingly put on the market.(Photos & Text von P. & M. Hoffmann)

It is not known whether this difference in colouration denotes sex, but in at least one pair showing the usual sexual differences (longer head and caudal peduncle, as well as enlarged and pointed pectoral and ventral fins in males) the male was striped and the female spotted. The L-number 134 was erroneously allocated a second time, to a Lasiancistrus-like catfish, which later received the replacement number 143.

B. prima is a small species, they can reach the size of about 6 cm. They like well planted, and since they are excellent jumpers also well covered aquaria. As for all air breathing fish there should be paid attention to a sufficiently high air temperature. Against the water chemistry B. prima places no special requirements. Breeding of these mouth breeders is not complicated, so that when diversified fed, if possible also with small living food, a new generation will appear sooner or later.

Red Cichlids of the species Hemichromis are generelly regarded as aggressive, but this prejudice is based on past years, when 160 ltr tanks were considered to be bathtubs and you mostly had to be satisfied with 60 ltr aquariums. To keep them in pairs, an aquarium of this size is in fact sufficient for Hemichromis sp. “Bangui”. But if you want to socialize the fish, it should be at least 160 ltr. Hemichromis sp. “Bangui” belongs to the more peaceful Cichlids of the species Hemichromis, but when they get into the mood for brooding, they know – like almost all Cichlids – how to defend their children emphatically. The breeding is actually no big problem, as they are not bound to any special water conditions and therefore brood regularly. Also the feeding is unproblematic, so that they can be even recommended to beginners with sufficiently big aquariums. Plants are not getting damaged. The fish are full-grown with six (females) to eight centimetres (males). It still is not clear, if it is an independent species or if we are facing a location variant of a kind already known. However, this Red Cichlid of Bangui certainly is an interesting enrichment to the aquarists offer.(Photo & Text T. Weidner)

This cichlid, which is growing up to approx. 20cm is living along the catchment area of the Orinoco, whereit mostly lives in slowly flowing or even standing waters. You often find it right in front of the shore, where it inhabits the upper water layer. Regarding the nutrition M. insignis is totally uncomplicated, because these are classic all-eaters . But they are not suitable for plant aquariums, as they often start to pull at the plants as they get older. On the other hand smaller fish are not safe from this species either and can thouroughly extend their menu. Mesonauta insignis – like all other flagcichlids – belongs to the kinds, which should not be kept under 26°C, as they would fade. If you increase the temperature to 30°C, however, they will show themselves in their most beautiful robe. Also slightly sour and soft waters increase their colour. M. insignis is a open breeder, who lay their eggs on plant leaves or roots. The leading of the young fish of flagcichlids is interesting to watch time and time again, since the shoal of young fish mostly stays above the body of the parental animals and not, as it is typical for cichlids, below the parents.(Photo & Text T.

An amazing variety of crustaceans can be found in tropical fresh- and brackish water areas. Only few species however are imported regularly. Recently this species was imported which comes from Sri Lanka, as one could guess from its name. O.ceylonensis is a pure freshwater species, with a carapax width of 6 cm and a colour varying from brown to red. Most crustaceans develop from free swimming larvae, a so called zoea phase, towards the adult and sessile phase. The zoea larvae of most brackish- and freshwater crustaceans float after hatching from riverine systems towards the sea where they spend their youth in seawater and migrate back to brackish or freshwater when they reached their sessile form. O.ceylonensis however stays its whole life in freshwater and has a direct development without a zoea phase. This makes this crab of course very suitable for the home aquarium.(Photo: Frank Schäfer, Text: Izaak den Daas)

Even Dr. Géry (France) could not determine this fish from just photos. This could mean that we have a new and undescribed species here. The only information about its origin is that it comes from Brazil, but no exact location has been given. There is a clear sexual dichromatism between the genders because the male have a mood depending colour ranging from orange to dark red of large parts of the body and the fins.

They prefer small live food, like cyclops or freshly hatched brine shrimps, but also frozen food will be taken eagerly.

From L 66 and their relatives (e.g. L 236) they can be distinguished by the form of the caudal fin, which is rather flag like and not reminding on a deep “C” .

Labeo calbasu

6. July 2007

Labeo calbasu the Orange-fin shark is a real king sized labeo. In its homeland (Pakistan, India, Bangladesh, Myanmar, Nepal, Thailand and South West China) it is a fish for consumption and therefore of importance in the asiatic aquaculture. With a size of up to 1m it is not a fish for the “normal” aquarium. Aficionados of the East Asian fish fauna possessing really large aquariums, can hold him together with Channa or Osphronemus species. In the wild Labeo calbasu is selective in feeding. Juveniles show a positive selection for zooplanktonic organisms. The adult showa negative selection for the zooplankton and a positive selection for decayed organic matter and molluscs. According to their large appetite they load the water very strongly, thus they are grateful for regular large water changes. In their habitats they occur in diverse waters types and so they have no special demands on waterchemistry.(Photo F. Schäfer, Text K. Diehl)

Microphis lineatus

6. July 2007

The species Microphis lineatus inhabits the (sub) tropical coastal waters of the American continent. This pelagic pipefish grows up to 22 cm lengths and has a very long slender snout with red spots and blotches. The body is brown or greenish above and pale below. There are very small white spots on the body and a dark line through both eyes. The brood care is practised by the males. Mature male Short-tail River Pipefish carry the eggs in a brood pouch on the ventral surface of the body. Large males can carry several hundred eggs. The breeding takes place in freshwater meanwhile they live most of the year in estuaries and coastal waters. Therefore salt should be added to the water. This pipefish takes only life food. Freshly hatched brine shrimps are taken eagerly. Flake or tablet food is generally not accepted.(Photo: Erwin Schraml, Text: Klaus Diehl)

Nandopsis salvini

6. July 2007

December 2006: At present we can offer a very beautiful, strongly red coloured variant of Nandopsis (Cichlasoma) salvini to you. They origin from South Mexico, Belize and Guatemala, where they live in to the Atlantic ocean heading streams. Like most Central American cichlids they are very easy to keep in middle hard water at pH values in the neutral range. With a maximum size of 20 cm they belong not to the giants, need however nevertheless sufficiently large tanks (starting from 150 cm). They can be kept together with other cichlid species. A socialization with small fishes is to be avoided, since they, according to their nature, regard them as food. They should be fed with substantial food, a granulated food with a high rate of shrimps can thereby affect the development of the red colour. They are easy to breed and their territorial and brood care behaviour make them to interesting tank inhabitants. An aquarium with Central American cichlids becomes actually never boring.(Photo F.

Vieja maculicauda

6. July 2007

Vieja (Cichlasoma) maculicauda the Blackbelt Cichlid is one of the larger Central American cichlids. Males can reach about 35 cm overall length. According to its size one needs voluminous aquaria, where their interesting social behaviour can be observed. In their distribution area (Atlantic slope, from the Usumacinta River drainage in Guatemala to the Chagres River in Panama) they live in the lower sections where the current is slow and go also into brackish water. Since they are able to tolerate brackish and marine conditions, they are unproblematic regarding water chemistry in aquaria. Fish of this size cannot be nourished with flake food alone. Beside granulated food and sticks they should be variedly fed. Here you can let your fantasy go and experiment a lot. Worms and insects as well as their larvae are greedily eaten, also vegetables should be offered, but here some individual differences exist in the readiness to eat these. But this individuality is a part of the attraction with the care of large cichlids. Over years one becomes acquainted with them, so that sometimes they nearly belong to the family(Photo F.

Palaemon concinnus

6. July 2007

Over an enormous range, that includes nearly the entire Indo Pacific those first as Macrobrachium “White Fingers” designated Palaemon concinnus can be found. Their bright white “shear-fingers” are very remarkable and give this from Sri Lanka imported species a special attraction. It is about a rather delicate, smaller species, thus one could try to socialise it with small fishes. Because it is a newly imported species we have no information to their behaviour in the aquarium as well as to their breeding. An opportunity to brake new ground is here offered to the Crustaceen Freak and surely interesting discoveries will approach.(Photo F. Schäfer, Text K. Diehl)

Barbus cf. callipterus

6. July 2007

This strongly at Barbus callipterus reminding barb reached us from the tropical west Africa. Whether it is a variant of the Clipper barb B. callipterus or a near related species could yet not be clarified. The further information refers to the general maintenance conditions of bigger barb species.They are social swarm fish, which should be held at the best in schools by at least 7 individuals. They prefer well – planted tanks (> 80cm) with open water for swimming. For the socialization further peaceful, active fish are suitable. Concerning their food barbs have usually no excessive requirements, but as other fish they like an occasional addition of frosted or living food to the commercial flake food diet. One is then often surprised, what energy is in a swarm of barbs, if e.g. living water fleas are offered to them.(Photo F. Schäfer, Text K. Diehl)

Danionella translucida

6. July 2007

Danionella translucida would have earned an entry in the Guiness book of world records. The largest measured individual was only 12mm long, thus acts it with this species around the smallest vertebrate anima. Apart from their extreme smallness the absence of sheds, as well as the high transparency of the dwarves are noticeable. They origin from Myanmar the former Burma, where they inhabit slowly-flowing, well planted streams. They place no special requirements for care, should not however naturally not with lively fish be associated. A small aquarium (50cm) is sufficient for a group of these interesting fish. Breed attempts should be undertaken f the fish are well fed with Artemia Naupliae and sieved life food. According to the waters in their habitat the water should be soft and easily sour. Reports on successful breeding are not known. (Photo: Erwin Schraml, Text: Klaus Diehl)

Corydoras armatus „spotted“

6. July 2007

April 2005: These beautiful animals where imported from Columbia. The literature however give Peru and Brazil as their place of origin. For more then 125 years ago these fish were described by Günther and since then hardly ever imported. The characteristic features of this catfish is the extreme long dorsal fin of which the first ray is coloured darkly. With exception the ventral side of the fish the whole body is marked with dark spots which are arranged in vertical line pattern. The head has no spots at all. The body form is high if you compare it with the very familiar looking C. loretoensis. From Brazil familiar animals have been imported however not with such marked pattern as these fish from Columbia.(Text: I. den Daas, Photo: F. Schäfer)

Poecilia caucana

6. July 2007

With an overall length of 3 – 5 cm the Cauca Molly (Poecilia caucana), originating from Colombia and Venezuela, belongs to the smaller living-bearers. Remarkably is the yellow – orange coloured dorsal fin and a violet metallically shining longitudinal line. The water equivalents (pH values of 8,2- 8.6, LF 360 and 420 Mikrosiemens/cm), based on different places where the animals are found in the area of the Rio Cauca, makes them to suitable aquarium inhabitants for the most Central European tap waters. They appreciate higher temperatures between 26 and 28°C. As industrious algae eater Cauca mollies are constantly on the search for food. All usual kinds of fish food are greedily eaten. With appropriate care a new generation will appear sooner or later.(Photo: Erwin Schraml, Text: Klaus Diehl)

Hemibrycon spec. „Paraguay“

6. July 2007

In the last years some quite difficult to classify new species of characins arrived from Paraguay. Usually they belong to the genera Creagrutus, Hemibrycon and Piabarchus. As a common characteristic a high swimming activity can be called for all species of this relationship. They need thus tanks, with a large free swimming area. Thus long stretched aquaria are ideal for them. There a strong current can be produced with the help of a centrifugal pump, in which they can organize their “swimming contests”. They like to jump, a complete cover helps to avoid losses. According to their origin they do not like it durably hot, an unheated aquarium is very pleasant and preserve the purse of the owner. They do not place increased requirements on their nutrition, living and frosted food are preferred, but they can also be fed with flake food.(Photo F. Schäfer, Text K. Diehl)

Phyllonemus typus

6. July 2007

The Spatula-barbeled Catfish, endemic for Lake Tanganyika, has a very special way of reproduction for catfish: they are biparental mouthbreeder. This small catfish is the only representative of its genus and can be easily distinguished by the long barbels on both sides of the upper jaw, which are ending into a spatula form. The total length of the fish is ca. 9 cm. Caring these fish in the aquarium should not be too difficult. These are nocturnal animals who will come out for feeding however during daytime. But mostly they rest, during the light phase, on dark places or caves, which have to be available in the fish tank. These are peaceful fish although any fish small enough to fit in their mouth, and therefore seen as food, might be eaten.(Photo: Frank Schäfer, Text: Izaak den Daas)

Hyphessobrycon bifasciatus

6. July 2007

The Yellow Tetra originates like its close related Von Rio Tetra from coastal rivers in southeast Brazil. With its pretty yellow basic colour it forms a beautiful contrast to it and other reddish characin species. As a schooling fish the Yellow Tetra should be kept only in larger swarms. Particularly in not too brightly lit up aquariums with dark ground their colours begin to shine. They need a free swimming area, the border regions of the aquarium should be densely planted. H. bifasciatus has neither against the food nor against the water chemistry to high requirements and can therefore be recommended to beginners for their society aquarium. Also for the first steps toward characin breeding they are suitable, since they already spawn in water with a light sour pH and moderate hardness and also the raising of the fry is not too difficult.(Photo F.

Apistogramma agassizii ,,Abacaxis“

6. July 2007

The fish in this picture shows the beautiful A. agassizii colour morph from the Rio Abacaxis, which lies in the middle part of the Amazon River in Brasil. Recently a number of new varieties are introduced to the hobby, originating from breeding as well as import of local colour morphs. We can only hope that these beautiful varieties will obtain a permanent place in our fascinating hobby. The breeding of A. agassizi in not very complicated if you are aware of the typical conditions of keeping Apistogramma. Soft and clean water with low pH, enough hiding places with caves having small openings for the females to be used as breeding places, are the basal conditions for successful breeding. With this know-how plus a small amount of aquaristical intuition nothing will be in the way for many hours of fascinating observation in front of the fish tank.

stingray-babies

6. July 2007

July 2005: During the night from Sunday to Monday it was about time: We got three babies. About five weeks ago we had received a female from Pantanal River and we immediately noticed on arrival that this fish was not alone: It was pregnant. After five weeks now of intensive care, these three babies were safely born in the night mentioned above. Their size is approx. 8 to 9cm Ø. The mother is approx. 35cm tall and was put into another tank right after delivery. It is noticeable that the young ones show much different markings than their mother. The father of the little ones could not be found out anymore.

Pseudancistrus spec. L 259

6. July 2007

Pseudancistrus spec. L 259 originates from the surrounding of the city Pimental at the Rio Tapajos. As all Pseudancistrus species the males of L 259 show a characteristic “beard” of Odontodes (dermal teeth) during the spawning season. Contrary to the popular Hypancistrus species L 259 are vegetarians. Therefore Zucchini, cucumbers and further vegetables should be added to the offered regular food (flakes and frosted food). With a size of 20cm they rank among the medium sized suckermouth catfish. Since males can get occasionally quite aggressive, roomy aquariums are needed. For maintenance higher temperatures (26 – 30°C) are recommended. There are no reports on a successful breeding in this species, so that suckermouth enthusiasts will surely discover some interesting news.

Labeo longipinnis

6. July 2007

december 2005: For the first time in Europe we can present Labeo longipinnis from the Congo River to you. This about 30 cm long growing Labeo is not noticeable by a particularly spectacular design or colour. Due to its lively manner, beautiful form and fins it can become nevertheless a genuine “eye-catcher” in the community aquarium. Since so far for their behaviour in aquaria no references are present , there is still a lot to discover. For the maintenance only roomy containers are suitable, one should also start with a not too small number of animals, since we know nearly nothing about its social behaviour. Labeo species can become quite incompatible at the age and then it is always favourable, when the aggressions can be distributed within a group. At the nutrition Labeo`s place, except what the quantity concerns, no increased requirements, a generous filtering unit should be always present with large sized bottom feeders.(Photo F.

Potamorrhaphis guianensis

6. July 2007

These fish belonging to needlefish (Belonidae) reach the aquariums of interested hobbyists only very seldom. These robbers, called halfbeak, come from almost all over Amazonia. You can find them also in the Orinoco catchment area as well as in the Guyana countries. These specialized surface fish are only suitable for the the hobbyists with restrictions because of their rapacious habits. Especially regarding the nutrition they are making heavy demands on their nurse. In the beginning they mostly only react to living or struggeling prey and you should therefore already have built up a feedingfish breeding or you can feed them with living insects, which will be taken from the surface. The animals are particularly excited, if crickets, flies or insects like that touch the surface. After the settling you can try to get the fish used to dead food little by little. Especially frozen white blood worms are well-tried, as they are floating quite long in the water – too quickly sinking food is not getting noticed. They are rather undemanding to the further care, you only have to provide aquariums big enough for the surface robbers, which will grow to 40cm maximum and they feel best within a small group of 3-6 animals. Therefore aquariums having a base of 150x60cm are the absolute minimum. The height of the aquarium is not important as only the first 20cm und the waters surface are used as living space. A socialization is quite possible, but the other fish should on one hand not be one of their prey and should on the other hand not be so agressive that they could be dangerous for the peaceful Potamorrhapis guianensis.(Photo & Text von T.

Dario hysginon

6. July 2007

Compared with Dario dario this species is hardly known by the general aquarists, although the males who obtain and guard their territory are looking very beautiful. Although they do not display the coloration like D. dario, they definitely show the same intense red colour. Unfortenately D. hysginon only shows his full colour when he is feeling well, and will look rather pale in the shops. As with all representatives of the Badidae family, these fish can be somewhat difficult concerning feeding and live food is essential although they might eat frozen food. Flake food however will not be taken. In a well-decorated aquarium, with enough shady places, the male will start defending a territory thereby showing his finest colours and with the appropriate female reproduction will start soon. The eggs and fry are usually not guarded but due to guarding the territory a certain amount of young will survive if one chooses the other tank mates carefully. Because D. hyginon will not reach a length of more then 3 cm large companions should not be kept with this beautiful little fellow.(Text & Photo: Thomas Weidner)
