After many years we received again this beautiful pastel colored dwarf cichlid from Guinea. Only in 2009 the species, which belongs to a group of species popularly also called king cichlids, was scientifically determined, before it was known in the hobby as “Pevicachromis sp. aff. roloffi Blue Fin”. The females of this species show – […]
The brook gobies (Rhinogobius) are as adult fishes pure freshwater inhabitants, which are found at most once in the brackish water of the lower reaches of running waters; but even this is the exception, not the rule. With 140 described species, 72 of which are generally considered valid, there is still a wide open field […]
We have the great ambition to open up new species for aquaristics again and again. Therefore it is not excluded that we also import species whose scientifically exact determination is not successful, because simply not enough scientific research has been done about the animals so far. The extremely species-rich genus Rhinogobius is a good example […]
From Peru we received wonderful, large angels (Pterophyllum). They have a yellowish to reddish back and many brown-red spots on the flanks. This exceptionally beautiful wild form has been called Pterophyllum leopoldi for decades due to a misidentification in aquarium circles. The “true” P. leopoldi originates from Brazil and is the fish always referred to […]
The 1980s and 1990s were the high times of traveling aquarists who wanted to shed light on Central American cichlids. And this succeeded more than satisfactorily! One of these amateur researchers in the best sense of the word was Hans-Günther Breidohr (1938-2017). In his honor Uwe Werner and Rainer Stawikowski named a cichlid Paratheraps breidohri, […]
Central American cichlids often require large aquariums. Not so much because of their swimming needs, but because they form territories and are often unbearably aggressive in aquariums that are too small. In large aquariums, on the other hand, this is hardly a problem. But there are also dwarf cichlids among the Central Americans, which – […]
It is a well known fact that the Betta splendens kept in the aquarium hobby as ornamental fish do not represent the species as it appears in the wild, but a domesticated fish. Initially this sport has been bred for combats, similar like sports of cocks and dogs. Only in the 1920ies, when supplying ornamental […]
The species status of Betta strohi is controversial. It is a form from the species complex around Betta foerschi (see https://www.aquariumglaser.de/en/fish-archives/betta-foerschi-bred/). Some authors consider B. strohi to be a synonym of B. foerschi, others a valid species. “Technically” the two differ by a rather inconspicuous feature, namely the eye line. In Betta strohi the line […]
The Scat is one of the fish species known to science almost from the beginning of scientific naming. Scatophagus argus was already described in 1766. This first description refers to a red scat. The name “rubifrons” for red scats that is always bandied about in the hobby is a purely fanciful name with no scientific […]
The cardinalfishes (Apogonidae) are a species-rich (ca. 370 species), mainly marine group of mostly small-bodied, mouth-breeding perch-like fish. Very well known species are the Kauderni or Banggai Cardinalfish (Pterapogon kauderni) or the Pyjama Cardinalfish (Sphaeramia nematoptera), several other species belong to the standard assortment of marine aquaristics. Only very few species have made it into […]
New catch areas bring immediately new species! That these are also wonderfully colored animals, as in the case of the bright red Nannostomus or the Apistogramma sp. Amaya (also called A. sp. Cenepa II) presented here, is surprising. Because Peru is really well collected! But let’s not be surprised, but enjoy the beautiful new imports! […]
At first sight one could think Labidochromis sp. “Mbamba” (the species is not yet scientifically described) is a typical mbuna of Lake Malawi: blue ground color, zebra stripes. But in reality Labidochromis sp. “Mbamba” is quite different. It is not a mbuna in the real sense, which are known to be algae/Aufwuchs eaters and aggressively […]
The kings of the discus fishes are the “Royal” varieties. A discus is called Royal if green or blue pattern elements are spread over the entire body surface. Among the green discus the Royal from Tefé in Brazil (which is also one of the type localities of S. aequifasciatus, i.e. the locality from which the […]
Snail cichlids are fascinating animals. They have chosen empty snail shells – in Lake Tanganyika there are large accumulations of empty shells of snails of the genus Neothauma – as their center of life. Neothauma snails are with a diameter of 4-5 cm relatively large snails from the relationship of the mystery snails. However, in […]
Red jewel cichlids are among the most popular aquarium fishes of all. For over 100 years, they have delighted aquarists around the world with their blaze of color and wonderful breeding habits. There is disagreement about the number of species, because these fish are very variable. Until now the red jewel cichlids were known under […]
From India (Orissa) we have received quite adorable tiger perch babies of the species Datnioides polota. Most of the only 1-2 cm long babies still have the dark baby dress, which is only interrupted in the front third of the body by a bright band. But single animals change already into the adult dress, which […]
Which species is the largest snakehead fish? Unfortunately, this question cannot be answered unambiguously, because the expression “angler’s lingo” has already become proverbial for uncertain statements. Anglers (and not only them!) like to exaggerate a little. But indisputable is: Channa marulius from India belongs to the top candidates for the race. The largest documented catch […]
The desert goby (Chlamydogobius eremius) is a wonder of nature in terms of temperature adaptability. Originally it comes from the desert of South Australia. There it can be very hot during the day, but very cold at night. The high heat capacity of the water prevents the fish from having to endure sudden temperature changes, […]
The Rio Nanay is a large, left-bank tributary of the upper Amazon River. It is considered a blackwater river. The Rio Nanay is home to Green Discus, which have always been sought after in the hobby. In the past, in the 1950s and 1960s, these precious animals came to us via the Colombian city of […]
The redhump eartheater (Geophagus steindachneri) from Colombia has had a regular place in the aquarium since it was first imported to Germany in 1972. There are numerous reasons for this. First of all it is very attractively colored. The males develop a red colored forehead hump, which varies very much in size. Over all: the […]
The Blue Dempsey is a beautiful blue variant of the normally rather dark colored Rocio octofasciata (formerly: Cichlasoma or Nandopsis octofasciatum). In the youth Blue Dempsey still have relatively many black color parts, the extremely intensive, then almost solid blue coloration develops only with increasing age. Presumably the animals are descendants of a mutant, which […]
The small cichlid Biotodoma cupido – it reaches about 12-15 cm total length, but is already sexually mature at 6-8 cm – is probably the most widespread cichlid species in Amazonia. Among experts there is cheerful disagreement whether all the different looking animals are only local color variants or independent species. Be that as it […]
The flood of newly discovered Badis species does not stop. It is astonishing that 23 new species of these fishes have been scientifically accepted in the last 20 years and only four in the 200 years before! Badis pallidus was only described in 2019; it belongs to the immediate relationship of Badis badis and cannot […]
We have the probably most beautiful of all snakeheads once again available in limited numbers. This species grows up to 50 cm long in the aquarium, but normally they reach only 20-25 cm in the wild; our currently stocked fish are 14-18 cm long. The species is endemic (i.e. only found there) in northern India. […]
In Apistogramma panduro from Peru (drainage of the Rio Ucayali, east of Jenaro Herrera) the females are absolutely emaciated. They are at least as beautiful as the males, if not more so; they fight as if they were males, and they show marked polychromatism. Polychromatism, or multicolorism, is when animals are individually, not species-specifically, differently […]
The beautiful cichlid Rocio octofasciata from Mexico is still known by many older people as Cichlasoma biocellatum. But all over the world young and old know him also under the popular name “Jack Dempsey”, although you have to be quite old to have experienced this legendary heavyweight boxer still in his active time: Jack Dempsey’s […]
For almost 20 years, ichthyologists have disagreed on which rule of the International Rules of Zoological Nomenclature is more important for the gouramis of South and Southeast Asia: the prime directive, according to which everything else must be subordinated to the stability and universal applicability of scientific names, or the various rules that regulate which […]
We have received an incredibly beautiful pair of wild caught Oscars from the Rio Tapajos. At least the male absolutely competes with the breeding form “Red Tiger Oskar” in color, but as we said, they are wild-caught! The sexes are difficult to distinguish externally in Astronotus, but the striking color difference and the expression of […]
When this beautiful Apistogramma first arrived in January 2003, we were thrilled. At that time we wrote: „King Barbarossa lives! A new, wonderful dwarf cichlid has now been imported from Peru for the first time. The species is still unknown both scientifically and aquaristically. The species is collected in the Tapiche river, a tributary of […]
The Australian northern trout gudgeon (Mogurnda mogurnda) belongs to the very few fishes of the fifth continent, which became native already before the 2nd world war in the aquaria. They are very beautifully colored animals, which in contrast to many other gobies are also relatively easy to breed. Unfortunately, the animals are only of limited […]
The Rio Tapajós in Brazil is a more than 800 km long tributary of the Amazon. It is also the largest tributary of the Amazon River and flows to its right side when viewed downstream. It is not surprising that the great Tapajós River contains numerous endemic species, i.e. species that only occur there and […]
The dwarf glass perch, Parambassis lala, is widely distributed in South Asia; it can be found in India, Burma and Nepal. In the past this dwarf, which never grows larger than 2-3 cm, was mistaken for the juvenile of other species, which is why completely wrong size data (up to 8 cm) and also completely […]
After many years we have once again imported the cute brackish water goby Mugilogobius chulae. The species grows only about 4 cm long and lives in brackish water regions and in fresh waters where the tidal influence is noticeable. Our animals come from Indonesia, but the species is widely distributed in the western Pacific region […]
The genus Mugilogobius comprises 33 species. The determination of living specimens is often uncertain, because the anatomical features (especially certain sensory pits), which show quite clearly in formalin preserved animals, are not recognizable in the living fish. Since there is hardly any picture material of surely determined animals, doubts often remain. Since the species reproduce […]
The dwarf gobies of the genus Pandaka are closely related to the bumble bee gobies (Brachygobius), but still much smaller. The species Pandaka pygmea was even considered the smallest vertebrate on earth for a long time, but it has since been outranked. The species Pandaka rouxi also usually grows to only 10-12 mm in length, […]
The Red Turquoise lines were among the first breeding forms of the Discus Cichlid, developed in the 1980s. Aquaristics had reached the point where wild-caught Brown/Blue Discus could be considered “cracked”. So one mastered their successful acclimation and breeding. Since wild-caught discus turn out very inconsistently – between simply brown and completely blue streaked animals […]
The “Pidgeon Blood” discus, which appeared in the early 1990s as a mutation in Asian discus breeding, revolutionized discus breeding. It combined two characteristics that discus breeders had previously only dreamed of: an early coloration, i.e. already 5-7 cm long juveniles look essentially like adult fish in terms of color. And a second advantage of […]
The color red is the dream color of many animal breeders. Red canaries, red swordtails, red guppies, red angelfish – wherever this was genetically possible, it was realized. With polychromatic fish species, e.g. with Apistogramma, where in nature always several color variants occur together, the red ones were preferred in breeding. And with the discus? […]
The Asian discus cultivars enjoy great popularity, because on the one hand they color very early (wild forms all look similarly unspectacular in 5-7 cm length) and on the other hand they are not very shy, so they can be presented well even in unfamiliar surroundings. Of the solid blue discus, the Blue Diamond, which […]
From the Colombian province of Caquetá we occasionally receive a magnificent Geophagus of the surinamensis group, which is obviously a scientifically not yet described species. Three color characteristics are used for the identification of Geophagus of this complex relationship: 1. the shape, position and size of the lateral spot in relation to the eye, 2. […]
Cyprichromis and Paracyprichromis are very special mouthbrooding cichlids from Lake Tanganyika. They live in sometimes huge schools and feed on small animals that they pick from the free water column. To attract the attention of females, the males can be very colorful. They do not occupy actual territories. The females, on the other hand, are […]
One of the most popular, because most colorful cichlids of Lake Malawi is the O-form of Maylandia estherae (synonym: Metriaclima e.). “O” stands for “orange.” As with many other species of Lake Malawi, several color forms occur within the same population of M. estherae in the wild. In the “normal” color form of M. estherae, […]
Of the seven scientifically described species of Astronotus, only two are currently recognized by most ichthyologists, namely A. crassipinnis and A. ocellatus; however, a third, A. zebra, is so distinctly different in color from the others that there is little doubt as to its validity. Now a new name has been established: the Oscar from […]
The Texas cichlid was successfully introduced to Germany and bred as early as 1902. In the meantime the species has undergone several name changes. In former times it was called Cichlasoma cyanoguttatum, today it is placed in the genus Herichthys and it is believed that the large spotted form as we can offer it right […]
Gold forms – also called xanthorists – are quite common in fish, even in nature. Ever since the beginning of man’s records of natural phenomena, there has been talk of golden perch, carp, crucian carp, tench and pike. Of course, such mutations occur much more often in breeding than in the wild, because there such […]
We have received very nice offsprings of this attractive red jewel cichlid (Hemichromis). The animals are 4-6 cm long at the moment and thus just at the border to sexual maturity. Fully grown they are with about 10 cm. Then they are much more high-backed and have a splendid red coloration, which is only indicated […]
Unfortunately imports from the Congo are becoming more and more rare, but when they do come, they usually include humphead cichlids (Steatocranus). There are almost always three species mixed. The strongest and most high-backed of them is S. casuarius, which can be recognized by the black scale centers. It has – due to mood – […]
The checkerboard cichlid (Dicrossus filamentosus) is the most typical dwarf cichlid in the habitat of the cardinal tetra (Paracheirodon axelrodi). It is found in Brazil (Rio Negro drainage) as well as in Colombia and Venezuela (Orinoco drainage). Males have a lyre-shaped caudal fin and grow to almost 8 cm long; the caudal fin of females […]
Similar to the fact that there are several red-backed angelfish populations, there are also several red or yellow-spotted wild forms. The ancestors of Pterophyllum sp. “Guyana Red Dragon” came from the Essequibo River in Guyana. Number and intensity of dots vary individually in each fish, but all specimens we currently received (they are now 5-7 […]
There is a lot of interest in special wild forms of the angelfish. Among the best known is the “Manacapuru Redback”, a very striking form. Because of the strong need for revision of the genus Pterophyllum, it is better not to call it “Pterophyllum scalare” scientifically, because what exactly this “real” scalare is has yet […]
The julies (Julidochromis) belong to the most popular cichlids from Lake Tanganyika. They are very beautiful, colorful and comparatively peaceful animals. Of course, for reproduction territories are formed and defended against other fish. All Julidochromis are recommendable aquarium fish, there is a suitable species for every aquarium. The largest is J. marlieri, of which we […]
The cute Flame Red Dwarf Badis (Dario hysginon) we have quite regularly in our stock. It originates from Burma (drainage of the Irrawaddy, Myitkyina District, Kachin State). More pictures of the species can be found here: https://www.aquariumglaser.de/fischarchiv/dario_hyginon_2__en/ Partly together with the Flame Red another dwarf badis occurs in nature, which is already mentioned in the […]
The dwarf cichlid Apistogramma agassizii has a distribution area that extends through practically the entire Amazon. With many of its genus comrades it is completely different, they often occur only locally and form then also location variants. Agassiz’ dwarf cichlid has so far successfully resisted all attempts to divide it. It is true that some […]
Whoever coined the name “Princess of Burundi” for this beautiful small cichlid: it is a brilliant name! The fish commonly known as Neolamprologus brichardi is by no means found only in Burundi, but is distributed in numerous color variants in Lake Tanganyika, which led to several scientific descriptions: Lamprologus savoryi pulcher, L. olivaceus, L. elongatus […]
The first reports about the brood care behavior of this dwarf cichlid in the early 2000s were a sensation. Mouthbrooding Apistogramma – one had never heard of it before. Later it turned out that things are complicated. Some of the females of A. barlowi, as this species is now called, show quite normal Apistogramma brood […]
The taxonomic status of this small cichlid, which has had quite a respectable aquaristic career as Amatitlania sp. Honduras Redpoint, is controversial. It is currently assumed that it belongs to the species scientifically described as A. siquia. Now this species is itself controversial and is seen by some scientists as a synonym to the old […]
In the north of India there are two Badis species, which are indistinguishable by color: B. blosyrus and B. assamensis. The only discernible difference that exists is the size of the mouth cleft. It is much larger in B. blosyrus and reaches below the center of the eye margin, whereas in B. assamensis the mouth […]
Are you in a phase of the hobby, in which nothing at all wants to work out concerning breeding? Then it is time for the emergency rescuer in all situations, the convict cichlid Amatitlania nigrofasciata. Although it is no longer available everywhere and at any time, especially in its natural form, it hardly ever disappoints […]
The humpheaded Frontosa (Cyphotilapia frontosa) from Lake Tanganyika has enjoyed great popularity for decades, although (or: because!) the species belongs to the bull class among the cichlids. Old males, which look downright bizarre with their forehead hump, can grow 30 cm long. Females generally remain smaller. In addition, C. frontosa is a crepuscular predator that […]
The largest and most splendid of all snakeheads belong to the relationship of Channa marulius. This species occurs in India and attains a maximum length of about 120 cm. The largest specimen ever collected is said to have had a length of 183 cm and a weight of 30 kg. But most often the fish […]
The double stripe (= the translation of the word diplotaenia) is still a rare occurrence in the aquarium. For successful breeding you have to reach pretty deep into the bag of tricks of water chemistry and the animals are also relatively unproductive. This unusual Apistogramma species originates from the black water of the Rio Negro, […]
For the first time we were able to import a beautiful Aequidens from Venezuela, which is probably Ae. superomaculatum. This species has been described scientifically only a few years ago – in 2015. Unique in the genus and also giving the name (superomaculatum = with a spot above) is the combination of a continuous lateral […]
More than 20 years ago (1999) Mario Wilhelm brought back from an expedition to Brazil for the first time this beautiful dwarf cichlid from the Rio Abacaxis. An alternative name to Apistogramma sp. Wilhelmi is therefore A. sp. Abacaxis. This river, a well known area for discus fishes, belongs to the drainage of the Rio […]
There is no doubt that Astatheros macracanthus is a fish for connoisseurs. This 20-25 cm long cichlid is distributed quite widely from southern North America to Guatemala and El Salvador. The species was scientifically described already in 1864, but in the aquarium it has always remained an absolute rarity. The reason is clear: in the […]
Few fish show as clearly how dynamic things can get in aquaristics as Cichla. These large cichlids are among the most popular food fish in South America, but until the turn of the millennium they were not considered very suitable for aquarium care: they were considered too large and too sensitive. In the meantime, however, […]
For the first time we could import this magnificent Heros from Venezuela in 2016. The animals should originate from a Rio Curare, therefore the name; however, no Rio Curare is known to us. We suspect the Rio Ventuari as origin. The fish are extremely colorful, otherwise everything speaks for the fact that it concerns the […]
For many Betta imbellis is the prettiest wild fighting fish at all. Of course, “the” Betta imbellis does not exist at all, because the widespread species looks somewhat different everywhere. It is the sister species to Betta splendens and in fact no human being is able to distinguish completely decolorized specimens of both species from […]
Besides the orange colored breeding form of this gourami from Burma (see https://www.aquariumglaser.de/en/fish-archives/colisa-labiosa-orange-2/) there is also a very attractive, deep red colored breeding form. In order to keep these wonderful animals in their bright coloration permanently, it is necessary to provide certain types of food (e.g. Cyclops, Spirulina or also special flake food). Without the […]
We have received beautiful offspring specimens of this magnificent Nanochromis from the Congo. Since the experts are not yet agreed whether this species is a color variant of Nanochromis teugelsi or a different species, we have chosen the name Nanochromis cf. teugelsi. The beautiful dwarf cichlids reach a length of about 7 cm in the […]
This snakehead, often traded under the name Channa cf. barca, originates from the northern Indian province of Assam. C. stewartii can reach a length of up to 30 cm (usually around 20 cm) and as a predatory fish should only be kept along with fish that are at least 2/3 of its body length. Besides […]
Sometimes it happens that even we run short in finding superlatives: in any case this fish deserves to create one! It is so beautiful…. H. compressa is a sleeper goby that lives free swimming in the water column. In contrast to many other gobies this fish is not a bottom dweller. In Germany the genus […]
Origin: Rio San Christobal = Laguna El Camalote, San Blas, Nayarit, Mexico The small town of San Blas, where the Rio San Christobal empties into the Pacific Ocean, is considered the northernmost place with a tropical climate on the Pacific coast of Mexico. The name Laguna El Camalote was originally applied to a marshland southeast […]
Our current Congo import contains again two species of the funny humphead cichlids: Steatocranus casuarius and S. gibbiceps. They look very similar to each other at first sight (and we can hardly avoid in wholesale that sometimes a casuarius is among the gibbiceps and vize versa), but when looking closely you can see that in […]
This beautiful cichlid has been swimming in the world’s aquariums since 1906 and has been delighting for generations with its varied behavior and beautiful looking brood care. The animals are typical open breeders with parent family, i.e. both parents lead the numerous brood. Confusion gave in the course of time due naming. For a long […]
The Emerald cichlid has become a bit out of fashion. This is a quite sad thing, for this impressive large cichlid – males can become up to 30 cm long, females always stay much smaller – is one of the most beautiful species of cichlid of South America. Once more we can offer now German […]
Black butterfly cichlids have been around for a few years and many breeders do an excellent job on them, so that really beautiful and healthy animals come on the market. We have now received a strain of Black Rams, in which the blue of the scales is limited to the rear half of the body […]
In very small numbers we have received this beautiful Geophagus as German offspring. The species reaches a maximum length of 20-25 cm and is exclusively found in the inlet of the Marowijne River, the border river between French Guyana and Suriname. One of the tributaries of the Marowijne is the Maroni River, known to cichlid […]
The Rio Madeira is a right tributary of the Amazon River and is considered the largest tributary in the world. Its origin is in Bolivia where it is formed from the confluence of the Rio Beni and the Rio Marmoré. It flows into the Amazon in Brazil at Itacoatiara. The Rio Madeira is a white […]
The pike cichlids (Crenicichla) are with 94 accepted species (and there are still a large number of undescribed ones) the most species-rich genus of cichlids at all. One of the most distinctly different species is Crenicichla jegui from the Rio Tocantins drainage. There the fish lives very hidden and was therefore discovered only when the […]
For the first time we can offer this magnificent breeding form of the black paradise fish. Our breeder writes about it: How did I become aware of these fish: In 2019, I saw a picture of blue paradise fish from Vietnam in a Facebook group for paradise fish lovers by chance. Being skeptical at first […]
The dwarf cichlids of the genus Biotoecus were shrouded in mystery for decades. The first species, B. opercularis, was scientifically described as early as 1875. It originated from the Amazon River basin in Brazil, a well-collected area for aquaristic purposes, and yet the first import was not accomplished until the mid-1980s and early 1990s. The […]
This season we received especially attractive Pterophyllum leopoldi from Brazil. Unfortunately, the animals do not like the photo tank at all and show there only a fraction of the wonderful colors – a magnificent green shimmer all over the body and a very nice red tone in the back – that well acclimated animals of […]
Only from few breeding forms is so well known, when they originated, as with Colisa lalia “Flame Red”. At the same time the fish decorated the covers of all aquaristic journals worldwide in the early 1980s, so sensational were they found. The animals were bred in the Lim Choa Kang area of Singapore, a rural […]
Nannacara taenia is with a maximum of 5 cm total length one of the smallest cichlids at all. Additionally it is absolutely peaceful and therefore an ideal fish for community aquariums. The species was described in 1911 from aquarium fishes believed to have been exported via Manaus. However, these animals were never found again in […]
What is the saying? Who does not ask, remains stupid. In the case of the rock cichlids of Lake Malawi, the so-called Mbuna, it is undoubtedly the garish, bright colors that initially attract attention and led to the much quoted comparison with coral fish. In fact, the colors of the mbuna have primarily the same […]
The Indian Dwarf Mudskipper, Periophthalmus novemradiatus, is the ideal aquarium mudskipper with its usually 6 cm length (in literature up to 10 cm are given, but we have never seen such large specimens, probably this statement is based on confusion with other species). In addition to its small size, it has many other favorable attributes: […]
Many rock dwelling cichlids (mbunas) of Lake Malawi live isolated on certain rocky shores. These are often miles away from other rocky biotopes, so geographic isolation leads relatively quickly to local color variations. Other cichlids of the lake, such as Sciaenchromis fryeri, are not bound to specific biotopes and occur accordingly throughout the lake. Although […]
Everything there is to say about these wonderfully colorful cichlids has already been said about another breeding variety, the Aulonocara Dragon Blood: https://www.aquariumglaser.de/en/fish-archives/aulonocara-dragon-blood-2/ The Orange Blotched are now one of the most common Malawi cichlids on the market. No wonder: there is hardly a fish species, which shows such a variety of bright colors, like […]
The convict cichlid Amatitlania (formerly Cichlasoma) nigrofasciata is really not a novelty anymore: it has been kept and bred in aquariums since 1939. The first aquarium animals of this very widely distributed fish in Central America came from the lakes Atitlan and Amatitlan in Guatemala. The genus to which the convict cichlid currently belongs was […]
Some time ago we introduced a short-finned fighting fish breeding form (“Pla Kat”) of Betta splendens as “Hellboy”. (https://www.aquariumglaser.de/en/fish-archives/betta-splendens-pla-kat-hellboy-and-giant-halfmoon/). Now we have received Pla Kat under this name from Thailand again, but they differ from the first Hellboys in color and fins. The new Hellboys have a halfmoon tail fin, which means that when the […]
Since a long time we received again a Congo import. Beside many other interesting fishes and novelties also the good old acquaintance Nanochromis parilus was among them. These beautiful, assertive dwarf cichlids are very common in the region around the capital Kinshasa. It is astonishing that they were described by science only in 1976. In […]
In the 1990s, when the large river cichlids of Brazil experienced a certain boom, also four Crenicichla species came to Europe for the first time, which were named Crenicichla sp. Xingu I – IV due to the lack of availability of a scientific name. All four grow quite large by ornamental fish standards, you have […]
There are many criteria, why to choose this or that fish for the aquarium. Those who like colorful fish should avoid Anabas. But who likes to observe biological peculiarities is well advised with the climbing perch. General information about Anabas can be found here: https://www.aquariumglaser.de/fischarchiv/anabas_de/. We have now once again imported climbing perch from Bengal. […]
Aulonocara are a specious and colorful genus of Malawi cichlids; because of their brightly colored dress they are called “peacocks” in English. They are small-animal eaters that selectively ingest small chunks of food. Another group of cichlids in Lake Malawi feeds on the algae and the microorganisms (= Aufwuchs) they contain, which grow on rocks. […]
The bluegray mbuna or the electric blue johanni (Melanochromis johannii) was imported so early (1972) from Lake Malawi for the hobby that one still made the effort to invent a popular name for it. This was later abandoned in view of the great number of species. In the wild, these fish, like many other Aufwuchs-feeding […]
The Rio Candelaria is a lowland river in Central America. It originates in northern Guatemala and flows through regions there and in southeastern Mexico whose jungle landscapes were almost untouched by man for a long time. The Rio Candelaria gained sad fame because the conquistador Hernán Cortez had the last Aztec ruler Cuautémoc, a fierce […]
One of the most beautiful freshwater fishes of all is Channa micropeltes. This snakehead lives in groups and its favorite pastime is eating. It is therefore constantly on the lookout for food and swims lively in a shoal through the aquarium. Although every word up to this point is true, it is still only half […]
The zebra cichlids of Lake Malawi were among the first cichlids to come to us from this great lake in the 1960s. At that time they caused real enthusiasm storms. Aquarists had no idea of the enormous diversity of species and forms that exist there. So the zebras were simply called “Pseudotropheus zebra” after one […]
The first documented domesticated form of the Siamese fighting fish (Betta splendens) was a Spadetail. That was in 1849. At that time certainly fighting fishes were bred for a long time, but they resembled more or less the wild fishes and were selected only for their fighting characteristics. The appearance of these animals was a […]
Fully grown angelfish of the various breeding forms are comparatively rare in the trade. The reasons are obvious: The breeding is time and space consuming, because they are still cichlids, which demand a certain individual space for themselves. That’s why XL angels have to be comparatively expensive. But occasionally such animals are in demand and […]
