One of the oldest aquarium fishes is the Buenos Aires tetra, of which the correct scientific name was only recently determined: Psalidodon anisitsi. To most aquarists, however, the species is probably still known as Hemigrammus caudovittatus (or Hyphessobrycon anisitsi), and it is under this name that it is found in most aquarium books. Since its […]
Nannostomus, also known as pencil fish, propel through the aquarium like small, colorful zeppelins. The unusual, somewhat stiff-looking swimming style makes them unique in the colorful world of tetras. There are quite a few species of Nannostomus-species, but the Red Pencilfish (Nannostomus beckfordi), which grows up to 6.5 cm long (but appears smaller due to […]
In 1915 the scientist Carl Eigenmann described a new tetra genus, which he named Megalamphodus. Type species is M. megalopterus, an aquaristic very well known species: the Black Phantom Tetra. In 1997 Megalamphodus became a synonym of Hyphessobrycon. Of the remaining species assigned to Megalamphodus in 1915 (ecuadoriensis, eques, heteresthes, melanotus, micropterus), only the Serpae […]
In the meantime it has turned out that these animals are Mylesinus paucisquamatus from the Rio Tocantins and the statement that they came from the Rio Xingu was a mistake. New species of large fish are still being found in the rivers of South America, despite they have been well studied. This is mainly due […]
We could import the beautiful species Pyrrhulina brevis already several times from Peru (see https://www.aquariumglaser.de/en/fish-archives/pyrrhulina-brevis-2/). This time they have a very intensive pattern in the anal fin, which reminds of an eye spot and corresponds with a similar pattern in the caudal fin. They are magnificent fish! For our customers: the animals have code 286754 […]
From the upper Amazon in Peru comes the beautiful garnet tetra, which grows 3-4 cm long. The very peaceful animal actually has characteristics like a carbuncle, a gemstone, which in fairy tales has the ability to make the owner invisible: because the eye and tail root of Hemigrammus pulcher shimmer like gemstones, but the individual […]
The tetras of the genus Leporinus (the genus name is a derivative of the Latin word “lepus” for “hare”) belong to the characteristic river fishes of South America. They owe their name to the shape of their mouth in combination with the elongated “hare teeth” in the lower jaw of some species, which reminded the […]
The Yellow Congo Tetra (Alestopetersius caudalis) originates, as the name suggests, from the Congo. However, it is almost never traded as wild catch, because it can be bred very well. With a final length of about 6 cm it belongs to the smaller species of the Congo tetra relationship. In the course of its aquaristic […]
The genus Curimatopsis comprised five described species until 2009 – now (2021) there are more than twice as many, namely 11! Curimatopsis can be divided into two major groups. First the C. macrolepis group with 6 species and second the C. evelynae group with 5 species. The best distinguishing feature of the two groups is […]
Already in 1894 the three-banded flag tetra (Hyphessobrycon heterorhabdus) was described scientifically; the animals on which the description was based came from the Brazilian state of Pará, more detailed information or illustrations are not available. From 1910 and in the 1920s, when the tetras advanced to the most popular aquarium fishes, also three-banded tetras came […]
In our last post on this impressive and beautiful tetra species from Colombia, we wrote “This tetra usually grows to around 5 cm long, with 8 cm given as the maximum size.” (https://www.aquariumglaser.de/en/fish-archives/pseudochalceus-kyburzi-4/). Since last week we know, this maximum size can actually be reached! Wow, that’s the first thing we thought of these huge […]
In 1957, when the first Green Tetras or Neon Costello (Hemigrammus hyanuary) were imported, the tetras were absolute fashion fish. Otherwise the comparison with the neon or cardinal tetra can hardly be explained, because H. hyanuary – which by the way is named after Lake Hyanuary in Brazil – is really nicely colored, but it […]
For many aquaristis the Bucktooth tetra, Exodon paradoxus, is simply the most beautiful tetra from South America. The splendid fish glitter and glimmer like diamonds and they never stay still. They hunt and hit their conspecifics permanently and an uneducated watcher may become quite concerned that the fish will eventually hurt each other. But this […]
The cardinal tetra, Paracheirodon axelrodi, is one of the most traded ornamental fish worldwide. It is a big exception in the ornamental fish trade, because it was mainly traded as a wild catch; it is different with almost all other important ornamental fishes, which are mainly or exclusively traded as bred ones. It is said […]
There is a nice story about the discovery of the king tetra, which we don’t know if it’s true, but it’s worth telling: In the Instituto Nacional de Pesquisas da Amazônia (INPA), Manaus, Brazil, aquatic plants were kept in an aquarium. Fish were actually not in it. But suddenly, as if from nowhere, cute baby […]
This very elongated Piranha can be confused hardly with other species because of its characteristic body shape. Type locality is the Rio Guaporé, Mato Grosso, Brazil. Aquaristic imports are mostly from Peru. Serrasalmus pingke from Venezuela was described from the Rio Apure. The holotype (54 mm long) is shown in MACHADO-ALLISON (2002); it has a […]
The identification of many Piranha species is difficult. One of the earliest described piranha species and therefore with many taxonomic problems is Serrasalmus humeralis. Valenciennes was the first descriptor in 1850, but there is no question that he had received the type specimen, for which he states “Amazon” as the type locality, from Castelnau. In […]
The characins of the genus Pyrrhulina can be better compared to cichlids than to other characins in terms of their behavior. The males occupy small territories in the breeding season, color themselves splendidly and defend the spawn energetically until the young hatch. The generic name Pyrrhulina means “small bullfinch” because the males of many species […]
The magnificent pacus of the genus Mylossoma that reach at most approximately 30 cm of length (the average length in the nature amounts to approximately half of this measure), are only with difficulty determinable. The last revision from 2018 (Mateussi et al.) distinguishes 4 species south of the Andes (another species, M. acanthogaster, occurs in […]
Once more we were able to import a new species of tetra from Venezuela which does not resemble to any species known to us. According to the supplier the animals were collected in small brooks in the surroundings of Puerto Inirida. There are no doubts that our new imports belong to the Astyanax relationship in […]
From Venezuela we could import Anodus orinocensis for the first time. As a young fish A. orinocensis often lives in mixed shoals with Hemiodus gracilis. The two species really look amazingly similar, but Anodus is a Aufwuchs eater, and also filters the water for small organisms and swims mostly in “normal” horizontal swimming position, while […]
Silver Dollars, which are the piranha relatives that eat mainly vegetable food, usually grow quite large, most species grow to over 20 cm, some to 40-60 cm long. The smallest known species is Metynnis lippincottianus, of which we can offer sexually mature specimens. They are currently 8-12 cm long, more than 15 cm total length […]
In great parts of South America there are large (up to 50 cm) piranhas, which usually become black when they are old. Another common feature of these piranhas is a red iris. It is currently common practice to refer to all these animals as Serrasalmus rhombeus because they are indistinguishable as adult fish. However, young […]
The Congo Tetra, Phenacogrammus interruptus, sometimes also called the Blue Congo Tetra, is the only one of the approximately 350 tetra species in Africa that is always available in pet shops. This is of course due to its beautiful colouring, which shimmers differently on the flanks depending on the incidence of light, the reddish-brown back, […]
From Peru we occasionally receive beautiful young Metynnis. We have not yet been able to identify them; they either belong to a scientifically undescribed species or represent a local form of M. maculatus. They certainly belong to the species cluster around Metynnis maculatus and we think that the final size, similar to M. maculatus, is […]

From the Rio Tocantins in Brazil we received wonderful, 11-14 cm long Serrasalmus rhombeus. This species grows 35 cm, maybe even 50 cm long, making it one of the largest piranha species of all. One can recognize adolescent S. rhombeus quite well by the combination of ruby red eye, a shoulder spot which is not […]
We just have a tank full of fully grown rosy tetra (Hyphessobrycon rosaceus) of the breeding form “White Fin” in stock. These magnificent fish are a real feast for the eyes. Read more about this form of fish, which is also known as H. bentosi or H. ornatus in the hobby here: https://www.aquariumglaser.de/en/fish-archives/hyphessobrycon-ornatus-white-fin-2/ For our […]
This tetra originates from Brazil (Rio Sao Francisco and Itapicuru). It reaches a maximum length of about 7 cm. Currently we can offer German bred specimens of this attractive schooling fish. For our customers: the fish have code 268613 on our stocklist. Please note that we exclusively supply the wholesale trade. Text & photos: Frank […]
The unusual genus Triportheus contains very interesting, somewhat larger species. Depending on the species these fish attain a length of 15-25 cm. Currently 16 species are distinguished that inhabit all major river systems of South America. From time to time we import members of the genus from Paraguay. Two species can be found there, namely […]
From Venezuela we recently received „feather tetras“. This is what we used to call tetras that have a striking black stripe in the anal fin, accompanied by a white line in front of it. In general, however, the term “feather tetra” is alternatively used to species of the genus Hemiodus or Hyphessobrycon copelandi. Our “feather […]
From the catchment area of the Rio Negro these interesting, rarely traded characins reached us. Brittanichthys axelrodi is a true black water fish, which should be kept at pH 4.5 – 6 and low hardness. Filtering via peat can be very helpful here. In addition to improving the chemical parameters, the bactericidal effect of peat […]
After several years we finally were able again to import this very beautiful tetra from Colombia once more. This species attains usually a length of about 5 cm, the largest one reported had about 8 cm in length. In respect of the general look and the behaviour Pseudochalceus kyburzi can be best compared with the […]
If ichthyologists were superstitious, they would surely believe that Serrasalmus geryi was sent to them so that they would not despair. No other species of piranha can be identified at all stages of its life as reliably and unequivocally as this endemic (i.e. it occurs exclusively there) of the Rio Tocantins in Brazil. The reddish-brown […]
Finally we could import one of the smallest fish species of the Amazon basin again: Nannostomus anduzei. They stay – including the tail fin – usually smaller than 2 cm. Our current import came via Manaus, so they are Brazilian animals; the specimens on which the original description was based came from the department Amazonas […]
Shortly after the first import of Argonectes longiceps we were able to import another feather tetra, which has not yet been seen, at least by us: Hemiodus thayeria. This beautiful, elegant fish comes from the border area of Brazil and Colombia at the Rio Negro. The type specimen was already collected in 1925 by Carl […]
When trying to identify piranhas, one often pokes in the dark. The differences between juvenile and adult forms are dramatic, both in terms of physical and color characteristics. Over the decades that we have imported young piranhas from all parts of South America, some characteristics have proved to be quite reliable in combination: 1- is […]
In the natural habitat of the cardinal tetra food sources are very scarce. So it is really astonishing how many species can exist there. However, many of them stay very small. Good luck for the aquarium hobby, for they all make very good ornamental species! Even a predatory species of that biotope is such a […]
We could import a quite unusual tetra for the first time in some specimens from Colombia: Argonectes longiceps. Although the species is inconspicuously colored, it looks quite attractive with its black and white tail fin pattern. They are peaceful animals which, in contrast to the closely related Hemiodus species, have a normal, i.e. horizontal swimming […]
For over 150 years a small tetra is known in science, that is placed due to the scaltion of the tail fin at present into the genus Moenkhausia, under the name M. lepidura. The species differs from all other Moenkhausia species, it was thought, by the coloration of the tail fin, in the upper half […]
This pretty tetra is a double of the very similarly colored species Moenkhausia agnesae. It remains however with 5,5 cm length smaller than M. agnesae, which becomes nearly 7 cm long. In addition, H. hexastichos, which occurs exclusively in the upper catchment area of the Rio Tapajós in Brazil, is not as quarrelsome as M. […]
This beautiful fish, a serrasalmid and thus a relative of piranhas a pacus, is still enigmatic for scientists. The species Metynnis fasciatus has been described on the basis of a young fish from Brazil (Rio Capiru). The type specimen is regarded as lost. The species is identical with M. hypsauchen in all respects exept the […]
According to the current state of science, the predatory tetra species Erythrinus erythrinus is widespread throughout practically all of South America: Argentina, Brazil, Ecuador, Peru, Colombia, Paraguay, Bolivia, French Guiana, Guyana, Suriname, Trinidad and Tobago and Venezuela. However, they look somewhat different everywhere, so that one must assume that in case of a modern revision […]
One of the longest known Leporinus species is L. friderici. It was already described in 1794 under the name Salmo friderici. The author, Marcus Eliser Bloch, writes: “This fish is a resident of Surinam’s waters. I received it from the present governor, the Lord of Friderici, along with several other fish. He has an excellent […]
The platinum hatchetfish, Thoracocharax stellatus, is regarded as biggest species of the hatchetfish. In the scientific literature, up to 6.8 cm of standard length (without tail fin) are indicated for the species. However, much smaller animals are always imported. The specimens that we currently offer as “large” have a standard length of about 3.5-4 cm. […]
One of the most common tetras from the Amazon and Orinoco is Hemigrammus bellottii. The species is easily recognizable by the golden longitudinal stripe and the red eye; other pattern elements (tail spot, fin coloration etc.) are usually missing. Only a shoulder spot can be present from time to time – depending on the mood. […]
The tetras belonging to the genus Pyrrhulina combine the advantages of two basic groups of ornamental fish. The first group are the schooling species that are always visible and swim merely in the open water: tetras and barbs. The second group has a fascinating behaviour and takes care for the brood: the cichlids and the […]
We have already mentioned it: currently we have three species of the genus Hoplias from Venezuela in our stock. The common wolf tetra (Hoplias malabaricus) has a huge distribution area, but it is very likely that this “species” proves to be a species complex consisting of several, at least partially undescribed species. With the “Hoplias […]
Right now we have three Hoplias species from Venezuela in our stock. Hoplias curupira belongs to the real rarities and is accordingly sought after among predatory fish fans. With a final length of about 40 cm the stocky species remains relatively small. It belongs within the genus Hoplias to the so-called H.-lacerdae group, which besides […]
We obtained a somewhat irritating import of a very rare species of tetra last week from Peru. In all probability, it is Moenkhausia simulata; however, our new import differs slightly from the previously known M. simulata in coloration. All other tetra species with a pattern of several horizontal stripes (Astyanax lineatus, A. kullanderi, A. superbus, […]
Three species of tetra in northern South America are obviously close relatives to each other and often confused: Hyphessobrycon loretoensis from Peru, H. metae from Colombia, and H. peruvianus, again from Peru. From these, H. loretoensis has been portayed here: http://www.aquariumglaser.de/en/hyphessobrycon-loretoensis_de_1188.html. Currently we were able to import the second Peruvian species once more, H. peruvianus, […]
Finally we managed to import again some specimens of this unusual “striped sock” from Venezuela. The species – there is just the one in the genus Synaptolaemus – was long known under the name S. cingulatus, until Britzki et al. discovered that the species described as Leporinus latofasciatus by Steindachner in 1910 was identical with […]
In the past years we received this rare headstander, scientifically described only in 2005, which is known from the Orinoco in Venezuela and the Tapajós in Brazil, only very occasionally as a by-catch from Venezuela. Mostly the animals were found among Anostomus ternetzi or Pseudanos trimaculatus. Now we could finally import some specimens of this […]
From Colombia we received an import of the striped wolf tetra, Hoplerythrinus unitaeniatus. The systematics of these almost over the entire South America spread fish is poorly understood. Only the one species, H. unitaeniatus, is recognized commonly, but there are a lot of synonyms, among them the (without justification) occasionally recognized species H. cinereus (Trinidad […]
It took until the year 2006 that the tetra specialists Axel Zarske and Jaques Géry found out that the species described as Copella nattereri was practically not present in the hobby and that the red spotted Copella, which was named C. nattereri until then, was not known to science yet! So Zarske and Géry described […]
We admit it: when we unpacked the animals, we were just disappointed. Colourless tetras, obviously young, with a black longitudinal line. Quite great. Because of the round head form they reminded of the genus Bryconamericus, a very species-rich and difficult to overview genus, and because we had to book them somehow into the system, from […]
Among he longest-serving rosy tetras in the hobby is Hyphessobrycon ornatus, even if the species has a true odyssey concerning the naming behind it and is called Hyphessobrycon rosaceus according to the latest state of affairs; before it was equated with H. bentosi. The first specimens arrived already in 1933 from Guyana. Breeding was not […]
From Venezuela we received a very nice color variation of Moenkhausia copei. The fish now look a bit like a stretched version of Moenkhausia collettii, where the shoulder spot so typical for M. collettii is missing and where the orange tail fin of M. collettii is red. We were able to import Moenkhausia copei for […]
For the first time we can offer this predatory tetra as German bred ones! Hoplias malabaricus is one of the most widespread species of tetra in South America; it is therefore suspected that it is more likely to be a number of externally very similar, so-called cryptic species. The offspring was bred with a pair […]
This piranha, described from Venezuela, is easily recognizable by its characteristic pattern in connection with the head profile, but still causes great confusion, as the fish in the trade come from completely different areas and are still indistinguishable. S. manueli was described as Pygocentrus manueli from the Río Paraguaza, middle Orinoco, Venezuela. The first description […]
The golden striped headstander, Anostomus tenetzi, has a very wide distribution in South America. It is recorded from Brazil, French Guyana, Guyana, Suriname, and Venezuela. The specimens on which the original descritption based, originated from Venezuela, and we were able to import them from there once more. This beautiful fish is among the most peaceful […]
There are two rather similar species of the silver dollar genus Metynnis with a pattern of black spots. They differ mainly by the (externally not visible) number of the gill rakes and the number of scales along the long side of the body, but also somewhat in relation to the body shape. We currently call […]
For the first time we could import, even if only in very limited numbers, this tetra from the Rio Xingu described only in 2004. The animal became known in 2001, when Rainer Stawikowski presented the fish as “Hemigrammus sp. Xingu” in the journal DATZ. The scientific description took place in 2004, twice and almost simultaneously: […]
Recently we obtained a shipment of piranhas from Peru. The fish are 5-9 cm long. At the first glimpse the shipment could be told apart into two phenotypes. First, there were fish with comparatively small spots, a lot of red coloration in the anal fin and a comparatively thin black border on the caudal fin. […]
We were able to import a new species of tetra from Venezuela which does not resemble to any species known to us. According to the collector the animals were collected in small brooks in the surroundings of Puerto Inirida. There are no doubts that our new imports belong to the Astyanax relationship in the broadest […]
For the first time we were able to import Acestrorhynchus heterolepis, which has been described scientifically as early as 1878 by Cope from Peru. Our specimens originate from Venezuela; it was a mixed shipment of these fish and A. microlepis*. A. heterolepis has two dark horizontal bands, thus reminding a bit in A. isalinae; however, […]
This small, about 4.5 cm maximum length reaching tetra belongs to the most attractive species of tetra at all. The species is very hardy and undemanding and can be easily bred in huge numbers. It is a fish of the subtropical regions and doesn´t even require a heater. In the wild, water temperatures between 16 […]

After many years we finally were able again to import this very beautiful tetra from Colombia once more. This species attains usually a length of about 5 cm, the largest one reported had about 8 cm in length. In respect of the general look and the behaviour Pseudochalceus kyburzi can be best compared with the […]
This is a very interesting and beautiful new sport of tetra. One can only guess that it belongs to the species Hyphessobrycon herbertaxelrodi, but there is no other species known in the hobby that fits better. Two characters make this fish very desirable: the extraordinary strong schooling behaviour and the intensive dark coloration of the […]
Obviously many different varieties – or do they even represent different species, who knows? – of the attractive pacu Myloplus (formerly: Myleus) schomburgkii exist. We obtained recently very nice specimens from Colombia, which are characterized by the very broad black band over the body. Our fish are 9-12 cm long and only subadults; Myloplus schomburgkii […]
This genus of South America gar characins contains only two species that are distiguished basically by the coloration of adult specimens (this means from about 15 cm length on): C. hujeta and C. beani. Both occur in Colombia; C. beani further occurs in Panama and C. hujeta in Venezuela. C. beani has an adult pattern […]
Currently we can offer wonderful, fully grown Tetragonopterus argenteus from Paraguay. The species attains a length of 8 – 12 cm. Formerly the genus Tetragonopterus was a catch-all genus for small characins from South America. Most of them are placed now in other genera, for example Hemigrammus, Hyphessobrycon, or Moenkhausia. But still the common name […]
Shipments containing juveniles of silver dollars or pacus are always surprise packages. The juvenile coloration of many species is simply unknown and juveniles look totally different than the adults. So we can only guess that in our current case the fish from Venezuela may belong to the species Myleus torquatus. The smallest babies, about 1.5-2 […]
This is a very unusual species of tetra. For sure the placement in the genus Hasemania is only tentatively and needs further investigations, as is explicitly pointed out already by the describers (Bertaco and Malabarba, 2007). It was the combination of lacking adipose fin (very unusual in tetras) and certain features of the dentation that […]
The systematics of the wolf tetras from Africa remain unsatisfying. According to the most recent literature there do appear two species in Nigeria, namely Hydrocynus forskahlii and H. vittatus. Both are very similar to each other and at times they were regarded to be mere synonyms. However, currently they are (again) treated as valid species. […]
Currently we can offer exclusively some top-rarities among the tetra family, all German bred. One of them is Hyphessobrycon piranga, which was introduced in the hobby by Peter and Martin Hoffmann in the German magazine Datz (issue 11/2017) under the unusual name of „Hyphessobrycon sp. non-red devil“. Despite the fact that the new tetra has […]
Among the smallest species of tetra is Hyphessobrycon elachys, the veilfin tetra from Paraguay. The species becomes only 1.5-2 cm long (standard length without caudal fin). The charming animals inhabit swampy areas in the Rio Paraguay drainage. The genus Hyphessobrycon, as it is currently defined, represents an artifical assamblage of species which are not very […]
For many aquaristis the Bucktooth tetra, Exodon paradoxus, is simply the most beautiful tetra from South America. The splendid fish glitter and glimmer like diamonds and they never stay still. They hunt and hit their conspecifics permanently and an uneducated watcher may become quite concerned that the fish will eventually hurt each other. But this […]
The barracuda tetras (Acestrorhynchus) a good aquarium fishes, although they are predators that prefer to feed on small other fish. Most species are medium sized – about 20-30 cm maximum length – but there do exist also dwarf species. Among the latter is A. isalineae. This species attains only 7.5 cm in standard length, this […]
The Blackstripe pencilfish has been described from Guyana scientifically back in 1909. Here he fish inhabits exclusively the Demerara river basin. The beautiful species attains a maximum length of 4.5 cm and is very peaceful. Formerly the fish was placed in a separate genus, namely Poecilobrycon, due to the long snout. In the meantime the […]
The African Longfin Tetra (Bryconalestes longipinnis, = Brycinus longipinnis) is a classic ornamental fish from Nigeria; we have it almost anytime in stock. Usually the fish traded are 3-5 cm long, which means that they are about half grown (maximum size reported for that species is 16 cm, but this is as rare as a […]
It is very difficult to determine gold tetras. The golden coloration is the skin reaction on a harmless infection with a parasite. If a tetra feeds the faeces of a fish-eating bird that contains the eggs of the parasite – a worm – in the intestine of the fish the eggs hatch and the larvae […]
Two species of pencilfish from Peru are very famous for their brillant red coloration: N. mortenthaleri and N. rubrocaudatus. Despite their small size – they become only 3-4 cm long – one should never underestimate their aggressivness. Especially N. mortenthaleri can become quite a problem for other small fishes in small tanks. So it is strongly recommended to keep these small fish in comparatively large tanks that allow other fish to avoid the attacks of the pencilfish. Given this one will enjoy a lot the wonderful Nannostomus.
Currently we have very nice wild collected N. rubrocaudatus in stock. The fish are about 3 cm long and full in colour.
For our customers: the fish have code 272264 on our stocklist. Please note that we exclusively supply the wholesale trade.

The longsnout distichodus has a very wide distribution in the Congo basin. The species attains a length of up to 40 cm; we recently obtain extremly charming, small juveniles. D. lusosso is an omnivorous fish; a great part of the food is plant material, so a planting of the tank is usually not possible. One […]
We obtained this charming ground tetra from Brazil. Melanocharacidium dispilomma has a very wide distrubution in northern South America. There are scientific reports from Bolivia, Brazil, the Guyana countries, Venezuela, and Colombia. There is a strange contrast between this very wide distribution and the fact that M. dispilomma has been described scientifically only in 1993. […]
The Striped Headstander is one of the most beautiful species of tetra from South America. It really looks like the big brother of the Threestripe pencilfish, Nannostomus trifasciatus. Anostomus anostomus attains a maximum length of about 15-18 cm. Sadly there are hardly ever exportations of ornamental fish from Guyana currently, so the beauty became rare […]
The Goldshoulder rosy tetra, Hyphessobrycon paepkei, has been described only a few years ago, the type specimens originated from our fishhouse. THe natural distribution is in the Rio Negro in Brazil. Usullay onyl a few specimens could be selected from shipments of other species, but now we are able to offer the beautiful Goldshoulder rosy […]
We are very glad to be able to offer this beautiful tetra for the first time now. The fish are German bred ones. The species has been described only in 2016. The natural distribution is the upper basin of the Rio Tapajós. This tetra is already a popular aquarium fish in Sao Paulo (Brazil) since […]
We want to remind on one of the first species of tetra that reached us from the area around Rio de Janeiro: Hyphessobrycon flammeus, the Flame Tetra. Since the first importation in the year 1924 the species is present in aquaria all over the world, for the fish are easy to breed and very productive. […]
The Serpae tetra is one of the most popular tetras at all. This is doubtless due to its intensive red coloration. In respect of the behaviour one cannot trust them too far. They have the nasty tendency to bite off pieces of finnage from other fish, also from conspecifics. From a scientific point of view […]

Leporinus steyermarki is a beautiful large tetra. It can reach a maximum size of about 30 cm and originates from Venezuela. In German, the fish is now and then named “Grey Leporinus” which is for sure not describing accurately the coloration of the animal. Maybe this name bases on a confusion with another of the numerous species of Leporinus.
Like all Leporinus, this fish is an omnivorous animal that takes a lot plant of material for food. Our specimens currently are 4-6 cm long and very peaceful against each other.
For our customers: the fish have code 265882 on our stocklist. Please note that we exclusively supply the wholesale trade.
Lexicon: Leporinus: Latin, means “hare-nose”. steyermarki: named for Julian A. Steyermark who led the 1953 botanical Venzuela Expedition of the Chicago Natural History Museum; the fish was discovered during this expedition.
Suggestion of a common name: Golden Spotted Leporinus

Only very rarely we obtain assorted „goldtetras“ in numbers. An exception of that rule is, however, „the“ gold tetra, Hyphessobrycon saizi (usually traded under the wrong name H. eos). But basically every tetra can become a golden one – they are only hard to find. We now received from Peru large, fully mature golden Nannostomus […]
We received a new species of tetra in number which reached us in former times in single specimens only from the Rio Negro region. Without any doubts the animals are identical with the tetra illustrated on page 472 of „the bible of tetra lovers“, Gery´s „Characoids of the world“. The caption says „Hyphessobrycon agulha, or […]
There is probably no other species of freshwater fish that has such a bilious green coloration as it is shown by the 4-5 cm long ground characin Ammocryptocharax elegans. We were able to import a few specimens from Brazil. However, one should know that these fish can change their coloration very fast and in case […]
We received once more the fantastic Moenkhausia agnesae from Peru. This is a larger species that can be kept ideally along with cichlids and catfish. Maximum length reported from M. agnesae is about 8 cm. Formerly this species has been often confused with M. simulata. However, the horizontal stripes in M. simulata are all black, […]

They have the nasty tendency to bite off pieces of finnage from other fish, also from conspecifics. From a scientific point of […]
For the first time ever we can offer this pretty and very interesting tetra from the Congo. The species is practically unknown among aquarists. The genus Monostichodus (formerly: Hemistichodus) belongs to the relationship of the subfamily Ichthyborinae (fin eaters). Many members of that group are specialized fish that feed almost exclusively on parts of fins […]
Every year comes a season for one of the most wanted fish or large show aquaria: Salminus maxillosus. And every year we have to look wether the ordered young fish really belong to that species. The Salminus are large (usually up to 60 cm, sometimes reaching even 1 m in length) predatory fishes hat feed […]
