These catfish have their funny name due to the fact that they make croaking sounds when taken out of the water. These sounds are decribed onomatopoeicly as „chaca“ by the natives. Usually Chaca chaca is imported from Bengal; the species is pretty common, but only seldom available, as it is not eaten by the local […]
The nase (Chondrostoma nasus) is a carp fish, usually 25-30 cm, maximum 50 cm long, which is native to Central Europe and Western Asia. As the species has relatively high demands on water quality, populations have declined sharply in many places, but the nase is currently considered „least „concern“ overall. Unfortunately, nase has also been […]
This close relative of the well-known and popular glass catfish Kryptopterus vitreolus (formerly: K. bicirrhis) is widespread in Southeast Asia. We have now been able to import this pretty species once again from Indonesia. The main difference between the glass catfish and K. macrocephalus is that K. macrocephalus has two dark stripes along the body. […]
When it comes to breeding forms, it’s easy to get into philosophy. This is because breeding forms of ornamental fish are an expression of cultural creativity. They serve only one purpose, namely to please. Accordingly, they reflect the zeitgeist at the time of their creation. Experience with garden plants, which have been cultivated and cared […]
We mistakenly received a Central American cichlid species from South East Asia under the name “Cichlasoma cyanoguttata”. After the 5-6 cm long fish had swum in a little, we went about identifying them and came to the conclusion that they were probably a Vieja species, most likely V. zonata. In such cases, however, it is […]
The wild forms of the currently very popular medaka (Oryzias) also appear in the trade from time to time in the wake of imports of the cultivated forms of these animals, whereas they were previously very specialized fish. The genus Oryzias – in addition to the popular Japanese name “medaka”, they are also known as […]
Once more we could import this very beautiful halfbeak from Indonesia. The halfbeaks of the genus Hemirhamphodon are adapted to blackwater in the wild. Thus they need – at least for the time of acclimatisation – very soft and acidic water. Maximum length of the species is around 6 cm (male), females stay smaller. The […]
Not only beautiful dwarf shrimps come from Lake Poso on Sulawesi (formerly: Celebes), but also these large cousins of the well-known tuberculate snail (Melanoides tuberculata). The bright color of the soft bodies of this Tylomelania, which is apparently a scientifically undescribed species, is particularly striking; occasionally the name Tylomelania scalariopas is used for them, but […]
Highly sought-after, large, magnificent and rarely on offer: this is Corydoras pantanalensis, which was given the code number C5 before its scientific description. For general information on the species, see here: https://www.aquariumglaser.de/en/10-catfishes/corydoras-pantanalensis-2/ We are very pleased to be able to offer some offspring of this species in the 3-4 cm size. The fish were bred […]
The rainbowfishes are a fascinating group of freshwater fishes from Australia and New Guinea; some smaller islands between these two major areas are also colonized by rainbowfishes, evidence that Australia and New Guinea once formed a common landmass when sea levels were much lower than today. This prehistoric landmass is called Sahul. Rainbowfish are almost […]
We have imported this pretty small freshwater mussel from Thailand again now. The species has a wide distribution in Asia. It is recorded from Thailand, Cambodia, Vietnam, India and China. Nevertheless very little is known about the species. Scabies crispata is a member of the Unionidae family. The central european large freshwater mussels of the […]
The thorny catfish are a very interesting and diverse group of catfish. Once again we were able to import the slender species Nemadoras elongatus from Peru, which can reach a total length of around 12-15 cm. At first glance, the fish are very reminiscent of the Hassar species, which they also resemble in terms of […]
The 6-7 cm long killifish Fundulopanchax walkeri was once very popular and widespread among enthusiasts of this group of fish, although it was not introduced to aquariums until 1952. This beautiful fish originates from Ghana, where it lives in the jungle. Geographically, the occurrence of F. walkeri is remarkable, as it is the only species […]
The Liberty Molly is an old acquaintance in the aquarium, but until recently it was considered to be a mere variant and synonym of the common Central American shortfin molly (Poecilia sphenops). Only in recent years have efforts been made to shed light on the darkness that makes the systematic classification of these fish so […]
Hemirhamphodon are among the most sensitive aquarium fishes. They especially do not tolerate transport well. They come from very soft, acidic water, so called black water. The conditions there are almost hostile to life, which means that there is hardly any bacterial contamination, because even for bacteria the food supply there is too poor. It […]
The large spiny eels of the Mastacembelus armatus complex are found practically throughout South and Southeast Asia. Within this huge distribution area very differently patterned animals occur. Some of them have been scientifically described as independent species, such as the very strikingly colored spiny eel with the large, circular spots on its flanks. It was […]
This very attractive snail species reaches us from Southeast Asia. Brotia pagodula is a viviparous snail that is endemic to the Moei, a border river between Myanmar and Thailand. The shell of this species becomes 4-5 cm long. The species is sexually separate, but the sexes are not externally distinguishable. Its strongly coiled shell with […]
Danio choprae, also known as the ruby or glow-light danio, comes to us from rivers and streams in Myanmar. At a length of 4 cm, they are already fully grown. As with many schooling fish, the effect on the observer increases with the size of the school. A group of 30 animals roaming lively through […]
The thorny catfishes of the genera Doras, Hassar, Hemidoras, Leptodoras, Nemadoras and Tenellus look quite similar at the first glimpse and have often been confused with each other in the past, both in scientific and aquarium literature; accordingly, there are always small question marks behind the identification of rarely imported species. From Colombia we have […]
Spring is approaching and with it the garden pond season. The simple goldfish breeding forms are best suited to this for a number of reasons, while high breeders (Oranda and Co.) have special requirements. But even with the “simple” forms – i.e. normal goldfish, comets, shubunkin and wakin – it is important to note that […]
The Danios are a very species-rich group of small to medium-sized carp fish, usually less than 10 cm in length. Most species have bright, iridescent colors and are excellent aquarium fish, some of which are standard in the global ornamental fish trade. The variety of forms makes it extremely difficult to get a complete overview […]
In the past, we were only able to present this beautiful tetra, which was only scientifically described in 2015, as a rare by-catch (e.g. https://www.aquariumglaser.de/en/09-characoids-tetra-relationship/hemigrammus-rubrostriatus/). However, we are now able to import these beautiful fish from Venezuela on a regular basis, as we have done again recently. The approximately 4-5 cm long animals are fully […]
White animals exert a special attraction on many people. In myths and fairy tales, it is often white individuals of a wild animal species that have magical properties. This explains why white rabbits, white pigeons, white mice etc. also have a special status among pets, and ornamental fish are no exception. The loss of color […]
The barb Luciosoma setigerum with the extremely aerodynamic shape originates from Indonesia. Despite the size the fish can reach – up to 25 cm – the peaceful and splendid colored fish is an ideal inhabitant for a community tank with other large barbs from Asia, like Bala sharks (Balantiocheilus) or Sahyadria denisonii. For our customers: […]
The rabbitfishes of the genus Siganus are well known to marine aquarists. They are beautiful animals that usually grow to 15-30 cm in length and eat mainly vegetable food. Until now no freshwater species of the genus was known, only Siganus vermicularis is regularly found as juvenile in the brackish water of river mouths. Now, […]
Easter is just around the corner, it’s getting warmer. Goethe has his Dr. Faust say on his Easter walk: “From the ice they are freed, the stream and brook, By the Spring’s enlivening, lovely look;” (translation by Edgar Alfred Bowring, 1853) and this also applies to garden ponds. For many, garden pond time is also […]
Some time ago we were able to introduce you to the large, magnificent Mastacembelus unicolor, which was sent to us by mistake as M. erythrotaenia (see https://www.aquariumglaser.de/en/22-spiny-eels/mastacembelus-unicolor-2/). The animals at that time were too large for the photo aquarium, so we were only able to take photos from the regular sales tank. Now we have […]
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 […]
Exactly 10 years ago, a new star appeared in the ornamental fish sky. A beautiful sky-blue (to stay in the picture) cichlid conquered the world. It was first offered to us in February 2014 under the name “Nannacara Neon Blue” from Singapore. However, it was clear from the outset that it was not a representative […]
A few decades ago, the Zamora catfish was the most commonly imported driftwood catfish. At that time it was identified as Auchenipterichthys thoracatus. It was not until 2005 that it was discovered that although the species A. thoracatus exists, it is not identical to the Zamora catfish. Its correct name is Auchenipterichthys coracoideus. While A. […]
What are the reasons for choosing this or that fish for your home aquarium? In the beginning, it’s probably basically the colors. Over time, you develop a feeling for the wealth of shapes in the realm of fish, then swimming behavior and body shape are added to the selection criteria. And finally, you delve deeper […]
The species of the Poecilia sphenops complex – P. butleri, P. mexicana and P. sphenops – are among the most common, most widespread and most diverse livebearing toothcarps in Central America. The diversity of forms both geographically and within each population is enormous. There are almost always large and colorful so-called alpha males and (from […]
At present, only one species of Pseudorinelepis is recognized by scientists, namely P. genibarbis. According to this assumption, the species is widely distributed in tropical South America and occurs in the Amazon and its tributaries as well as in the Orinoco and its catchment system. According to this theory, the color differences observed in living […]
Hardly any other genus of loricariid catfish, often referred to as L-catfish, is as widespread and important in aquariums as Ancistrus. Practically every aquarium is home to a few of these problem-free animals, which do an excellent job of cleaning the glass, look bizarre and hardly disturb other fish. But when it comes to identification […]
Oscars (Astronotus) are naturally very variable in color. In addition to wild-colored animals, cultivated forms have also enjoyed great popularity for decades. Why is the Oscar called Oscar? To be honest, we don’t really know. But it is certain that the name originated in the USA. In 1936, an article by E. W. Clarke on […]
The freshwater angelfish (Pterophyllum) is one of the most popular ornamental fish of all. The species name Pterophyllum scalare is usually chosen for the cultivated forms, although this does not describe the situation correctly from a scientific point of view. The cultivated forms, which were mainly created in the 1940s to 1960s, are partly based […]
The Thorny Catfishes (Doradiae) are a small family of exclusively South American catfish. Currently 41 genera containing 127 species are known, but continuously new species become discovered. The largest species attain a maximum length of more than 100 cm. The world record for Opsodoras niger is 120 cm and a weight of 20 kg. The […]
In 1981, the first report appeared on a Geophagus species imported as by-catch, which the author, Rainer Stawikowski, initially referred to as the “Yellow Cheek-Stripe Eartheater“. The relatively slender species is very much out of the usual range of Geophagus, both physically and in terms of brood care behavior. Nevertheless, it took until 1992 for […]
The rosy barb (Pethia conchonius) was first brought to Germany in 1903 and has since developed into a worldwide classic among ornamental fish. It is one of the 100 most commonly traded species. They are hardly ever wild-caught, although these fish are so common in their native country India that they are traded in large […]
Like so many cichlids, angelfish also develop different-looking forms within their large distribution area. Whether these forms are classified as independent species, as subspecies or as color variants is ultimately a matter of taste and a philosophical issue. There are also individual differences within each population; in the case of the angelfish of the Rio […]
We can currently offer all three striped Panaque from Colombia, namely L330 Panaque nigrolineatus laurafabianae (Colombia: upper Rio Guaviare drainage), L190 Panaque nigrolineatus nigrolineatus (Colombia/Venezuela: Rio Meta and lower drainage of the Rio Guaviare) and L191 Panaque cf. titan (Colombia: Rio Caguán, drainage of the Rio Caqueta). We have comparable sizes of all three forms […]
The cherry barb has recently been assigned a new genus (see https://www.aquariumglaser.de/en/08-carp-like-fishes-2-barbs-minnows-carps-goldfish-etc/new-generic-names-for-former-puntius/). In the genus Rohanella – named in honor of Rohan Pethiyagoda, one of the most prominent ichthyologists of our time – there is only one species, R. titteya. DNA studies have shown that the different geographical locality variants are not genetically far enough […]
From two different suppliers, one from Peru and one from Colombia, we have received a catfish of the genus Batrochoglanis, whose identification to species level is not possible according to the publications to date. Representatives of the genus Batrochoglanis are not difficult to recognize as such; typical of the genus is the shape of the […]
We have again received a nice number of beautiful domestic offspring of this extraordinarily beautiful black paradise fish (Macropodus spechti “Royal Blue”). For the history of this variant see https://www.aquariumglaser.de/en/25-perchlike-fishes/macropodus-spechti-royal-blue-2/ In the meantime, the fish have been further developed in terms of breeding and are preferably bred with animals that – very similar to Belontia […]
Brocade is a very heavy, strong fabric. It used to be considered particularly noble and precious, as the base fabric was made of silk and gold and silver threads were woven into it. All in all, brocade was a fabric for ceremonial robes and similar purposes. The golden barb is called brocade barb in German […]
We recently introduced you to the Jupiaba anteroides from the Rio Cenepa in Peru, which we imported recognized for the first time (see: https://www.aquariumglaser.de/en/fisharchive/jupiaba-anteroides-2/) In the meantime, the few specimens still remaining with us have got into the mating mood and the males have taken on a quite astonishing mating coloration with a tomato-red belly. […]
With currently 45 recognized species (as of January 2024), the genus Gymnotus is the most species-rich group of New World knifefish. Research into the species diversity of Gymnotus only began at the turn of the millennium; until then, only around 12 species were differentiated. From 2001 onwards, comprehensive papers with species descriptions and phylogenetic analyses […]
The Rita catfish, Rita rita, is one of the most sought-after food fish in the Ganges-Brahmaputra system in India, Pakistan and Bangladesh. Although the species has a large distribution area and is classified as “least concern” overall, certain local populations are apparently overfished. This species, which reaches a length of up to 150 cm, is […]
Small wild-caught fish Discus cichlids, like all cichlids, only develop their full coloration when they are largely mature (i.e. approx. 15 cm long in the case of discus). This is generally known and one of the reasons for the popularity of Asian color breeds, as they already show their full color at lengths of 7-9 […]

The first glance into an aquarium with this breeding form of Xiphophorus maculatus may only reveal beautiful blue platies with a large tail root spot (“Moon” or “Mickey Mouse”). But a second look shows that there is more to these fish, especially the males! They are multi-colored. Dominant, optimally colored males of this breeding form […]
The pretty Thiara winteri from Indonesia with its pagoda-like shell, the longitudinal ribs of which are more or less (this varies greatly from individual to individual) spiky at the junctions of the coils, belongs to the group of trumpet snails relatives to which, for example, also belongs the very common red-rimmed melania (Melanoides tuberculata). The […]
The predatory catfish Calophysus macropterus belongs to the medium-sized species of the Pimelodidae (antenna catfish), the largest representatives of which can reach a length of around 2 meters. The largest Calophysus measured to date (there is only one accepted species, C. macropterus) is said to have been approx. 60 cm long, but animals as long […]
We have received a small number of these new, really unusually marked Rineloricaria sp. Jacareacanga – named after the place where they were found on the Rio Tapajós. Many thanks to Ingo Seidel for the information on the origin of these catfish! Our largest animals are about 15 cm long. They are real beauties, who […]
The question of which scientific species names should be given to the various discus cichlids is a controversial one. There is agreement that all Symphysodon populations are relatively closely related to each other and that preserved specimens cannot be identified with certainty without color and location; the only exception is the Heckel discus (Symphysodon discus), […]
For a variety of reasons, aquariums were predominantly small until the 1960s and held 10-100 liters of water. Accordingly, aquarists focused on small fish. It was only when the cichlids of Lake Malawi were imported that the trend changed. These “coral fish of freshwater” need large tanks due to their high intraspecific aggressiveness and soon […]
Perhaps the most unusual of all Molly breeding forms is Chocolate. This is because it is a dark-colored albino! At first, this sounds like an absolute contradiction in terms, like a “round corner” or the “black mold”. But it’s still true. In the chocolate molly, the red eyes of the albino meet a chocolate-colored body. […]
Dear fish friends, we are currently rebuilding something and therefore there will be no newsletters for a short time. We will hurry, we promise! Best regards The Aquarium Glaser team
The species characteristics of this dwarf cichlid from Peru are: distinct underbelly stripes, an orange “axillary spot” (the attachment point of the pectoral fin is intensely orange in color), a more or less distinct orange zone on the belly and a tail fin that is tipped at the top and bottom in old, fully developed […]
Who can keep track of the many, many breeding forms of livebearing toothcarps? Aquarists interested in guppy genetics know that there are thousands of possible color and fin combinations in these animals. Many of these (by no means all) can be bred in pure lines, given the appropriate ambition and perseverance. Can you blame the […]
Currently we have wonderful flounder whiptail catfish from Peru in stock. They are currently 10-13 cm long. These sizes give only the body length, as in Planiloricaria there is a filament on the upper lobe of the caudal fin that is as long as the body! Maximum length given in literature is 35 cm. Nevertheless, […]
New times bring new methods, new methods bring new findings. Who knows, perhaps Jack the Ripper would have been caught if the criminal techniques of fingerprint and DNA analysis had been available in 1888 when he committed his murders. Even before Jack the Ripper’s time, the many, many local forms of the common panchax (Aplocheilus […]
Small freshwater gobies have recently attracted the attention of more and more scientists and, as a result, new species are constantly being discovered and old, almost forgotten species rediscovered. The genus Mugilogobius currently comprises around 30 species. It is not possible to be more precise because individual species are placed in different genera by different […]
Recently we could present you a magnificent, deep red new pencil fish (see https://www.aquariumglaser.de/en/fish-archives/nannostomus-sp-super-red-2/). Thereby we mentioned a second species, the “Cenepa Super Red”, which we unfortunately only knew from internet pictures at that time. We now manage to import these magnificent animals on a regular basis. The “Cenepa Super Red” differs from the “Super […]
Sometimes supposedly small details are decisive, for example when it comes to species differences. There are two species of snakehead (Channa) that occur geographically close to each other in Burma (Rakhine State): Channa pulchra and Channa ornatipinnis. Both look quite similar and grow to a similar size (20-25 cm), but they differ considerably in their […]
The blackline rasbora is a well-known aquarium fish that has been delighting ornamental fish enthusiasts since 1954. This completely peaceful schooling fish is ideal for enlivening the middle and upper water layers. Rasbora borapetensis, whose species name was chosen after the place where it was first found (the 220 km2 Bung Borapet swamp in Thailand), […]
The orange chromide, Pseudetroplus maculatus, is a well-known aquarium fish and has not disappeared from the tanks of enthusiasts since it was first introduced. Recent studies indicate that the three species of cichlids from India (Pseudetroplus and Etroplus) are not so closely related to the cichlids (Cichlidae), but rather to the damselfishes (Pomacentridae). However, this […]
The Keyhole cichlid (Cleithracara maronii, formerly Aequidens maronii) is a well-known aquarium fish that has only rarely been imported to Europe as a wild catch since its first import in 1936. The demand is covered by captive breeding. Although the species has no striking colors – the very varied pattern consists of brown, grey, beige […]
The nerites (Neritidae), also known as racing snails, are very popular. Their beautiful coloration is one of the reasons for this, but also their excellent properties as algae cleaners, which (if you keep enough specimens) reliably keep the aquarium glass clean. Plants, on the other hand, are left completely alone. And there is no unwanted […]
The albino breeding form of a weather loach (Misgurnus) originating from subtropical Asia is currently enjoying a constant increase in popularity. We call it Misgurnus anguillicaudatus, but this is only a makeshift name, as the correct species names of the Asian Misgurnus species cannot currently be determined. The albino weather loach reaches a length of […]
The red mangrove crab or red Thai crab is by far the most popular crab for paludaria (combined aquaria and terraria). What is not yet widely known is that it was placed in a different genus – Manarma – in 2020. In the hobby, the species name is also traditionally misspelled. The correct name is […]
This freshwater goby, which attains a maximum length of 4-5 cm, is one of the most attractive discoveries of ornamental fish of the last years. However, in the beginning the fish were extremely expensive. Currently we can offer them for a comparably moderate price. Rhinogobius zhoui originates from China. In the natural habitat – brooks […]
For the first time ever we obtained a species of Batasio from North Bengal in India. They belong to the species Batasio fasciolatus, which was described scientifically only in 2006. One can see that the determination of species of Batasio is not that easy keeping in mind that B. fasciolatus was already subject of an […]
The Amano shrimp, Caridina multidentata (formerly: C. japonica) is the most popular of all aquarium shrimps. However, it is only available seasonally from wild collections. However, as there is a year-round demand, the species is bred on a large scale. For German offspring, see here: https://www.aquariumglaser.de/en/31-crayfishes-shrimps-crabs-snails-mussels/amano-shrimp-now-also-available-as-german-offspring/ When animals are bred, sooner or later color or […]
After many years, we have once again received one of the most extraordinary tetras in Brazil: Moenkhausia cosmops. This species was only scientifically described in 2007. Until now it has only been known from the upper reaches of the Rio Paraguai and Rio Tapajos basins in the state of Mato Grosso: Rio Juba, Rio Juruena, […]
The loaches of the genus Leptobotia differ from all other botiide loaches in that the razor-sharp, sickle-shaped spine under the eye, which all botiide loaches can erect and lock in the event of a perceived or real threat, is only single-pointed. In Botia & Co. it is usually two-pointed. At present, around 20 species are […]
At least three species of mollies are the source species of the numerous breeding forms of these fish that exist today: Poecilia sphenops, P. latipinna and P. velifera. P. mexicana may also have been involved, but this is unclear as this species was long regarded as a synonym of P. sphenops. The scientific differentiation of […]
The genus Sarcocheilichthys from China has the potential to become a new star in the ornamental fish sky. There is a complex of small (6-7 cm) species within the genus in southern China, which are characterized by a broad longitudinal band. The males of all three species develop very pretty vermilion fins at spawning time. […]
In the huge variety of species of Corydoras, four species stand out in particular due to their bright orange pectoral and dorsal fin spines: Corydoras sterbai, the associated long-snouted C. haraldschultzi, C. gossei and its long-snouted counterpart C. seussi. We aquarists are naturally delighted by this sight, but we should not forget that these are […]
This beautiful loricariid catfish was already scientifically described in 1941. The type locality is the drainage of the Rio Jaguaribe in the Brazilian state of Ceará in the north-east of the country. The maximum length published to date is around 13 cm (10 cm without caudal fin). The Rio Jaguaribe is notorious for its erratic […]
The Celebes Rainbow, Marosatherina ladigesi, is perhaps still remembered by some readers as Telmatherina ladigesi. The species lives endemically (i.e. – seen worldwide – exclusively there) in cool karst streams in the area around Bantimurung, Maros karst, Sulawesi Selatan; Sulawesi belongs politically to Indonesia, but zoogeographically to the Australian region. In former times the big […]
Formerly this species of glass perch was the most common found in the trade. It has a very wide distribution through Thailand, Vietnam, Cambodia, and Laos. However, Parambassis siamensis was most often mis-identified and traded under the name “Chanda wolffii”. P. siamensis is very similar to the Indian species P. ranga. Both are distinguished by […]
If aquaristics were exclusively about colors, there would hardly be any need for species other than Rubricatochromis. The “Neon” is probably a breeding form created by crossing and selection, in which the blue iridescent spots, which most red jewel cichlids have, are combined to form larger areas. In terms of body shape, Hemichromis sp. Neon […]
The drums (Sciaenidae), to which Boesemania microlepis belongs, are mainly known from the sea. Only a few of the approximately 300 species live permanently or occasionally in freshwater. These fish are known as “drums” because they make a very audible sound. Larger schools of these fish have already triggered submarine alarms because they cast a […]
The genus Spatuloricaria comprises currently 11 accepted species. Members of this genus are large, splendid whiptail cats. There is probably no species that stays smaller than 30 cm in length, some become definitely larger. This means that the fish have to be kept in large aquaria. Spatuloricaria are sensitive against poor water quality. Thus a […]
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 […]
The large, wood-eating Panaque species have their loyal fans. Although these animals only reach us in relatively small numbers, they have been on offer from exporters for decades. This includes L90, the variably colored Panaque bathyphilus from Peru, which can easily reach a body length of 60 cm in old age. We have reported on […]
It has been almost 20 years since we were able to offer this beautiful armored catfish from Brazil. Corydoras sarareensis, which was given its species name after the Rio Sarare from which it originates, was only scientifically described in 1995. Prior to this, the species was known as “C23” in the hobby. The Rio Sarare […]
The small mouthbrooders of the genus Pseudocrenilabrus have been kept and bred in the aquarium since the beginning of modern aquaristics – in the 1880s. The species P. multicolor was once so popular that it was simply called “the mouthbrooder“, although it was already known at the time that there were hundreds of species of […]
The name for this hillstream loach may be new to you, but you know the animal. In fact, Beaufortia kweichowensis is or was the most common hillstream loach in the trade and was traded as “China Pleco”, “Chinese Butterfly Sucker” or “Butterfly loach”, with the scientific name usually being Beaufortia leveretti. Beaufortia leveretti really does […]
It’s hard to believe, but this striking and large catfish – the species reaches a final length of approx. 85 cm – which is also widely distributed in Amazonia (Ecuador, Peru, Colombia, Bolivia, Brazil) was only discovered in 1981! It was described in the genus Merodontotus, which was created especially for it, but is now […]
Within the true mudskippers – these are the species that actively leave the water and search for food on land, etc. – there are two genera: Periophthalmus (19 species) and Periophthalmodon (3 species). They do not differ externally, only in the structure of their teeth. We have now received Periophthalmodon septemradiatus from India, a beautiful […]
The genus Pseudorasbora comprises only five accepted species. Representatives of the genus can be easily recognized by the upwardly directed mouth fissure, a characteristic that is rare within the carp fish (Cyprinidae). Pseudorasbora is originally distributed in East Asia (China, Russia, Japan). One species, P. parva, was unintentionally introduced in the 1970s with food fish […]
Just a few decades ago, the Peacock Basses from South America (genus: Cichla) were considered almost unsustainable for aquaria, but nowadays they are bred regularly and in large numbers. The latest craze is Cichla kelberi “Spider”, a breeding form whose origin is not yet known. The photos show our current stock, 16-18 cm long specimens, […]
The small rice fish Oryzias latipes was domesticated by humans at an early stage and was one of the very first exotic fish species to arrive in Germany before the turn of the 19th and 20th centuries. It became the pet of geneticists, so to speak – especially in Japan – who conducted and still […]
It’s amazing how many new and extraordinarily beautiful tetra species have appeared in recent years. Among them is an Inpaichthys species that has not yet been scientifically recognized and is referred to as the “Red Eye” by those who catch it. The I. sp. “Red Eye” differs from the well-known king tetra (I. kerri) not […]
The beautiful Corydoras sychri from Peru – it lives in the Rio Nanay – is unfortunately only occasionally available. We currently have very nice, large specimens in stock. There are some species that can be confused with C. sychri. The best known is C. atropersonatus, which also comes to us from the Rio Nanay. C. […]
We recently succeeded in importing the species Hyphessobrycon epicharis, which had previously only been imported in very small numbers (see https://www.aquariumglaser.de/en/09-characoids-tetra-relationship/hyphessobrycon-epicharis-2/ and https://www.youtube.com/watch?v=RBofRyOLk3g). Now we have succeeded in importing once more that species that is unmistakable due to its distinctive shoulder spot.
