  • Nothobranchius korthausae

    6. March 2023

    The small island of Mafia is located off the coast of Tanzania. It is the southernmost island of the so-called Zanzibar archipelago and has an area of about 435 km2. In 1972 Edith Korthaus, editor of the magazine “Das Aquarium”, visited the island. She found there a yellow Nothobranchius, which one year later – in […]

  • Leporellus vittatus

    3. March 2023

    Finally we were once more able to import some of the very rarely offered Leporellus vittatus from the Rio Xingu in Brazil. This extraordinary species attains a length of approximately 25 cm and belongs to the headstander tetra relationship. However, in Leporellus the air bladder is mostly reduced and so the fish live strictly bottom […]

  • Corydoras sp. “punctatus Nanay”

    3. March 2023

    From the Rio Nanay in Peru comes this beautiful spotted armored catfish, which probably belongs to a scientifically undescribed species. It was first mentioned and pictured in aquaristic literature as Corydoras punctatus in the 1930s, but C. punctatus is a completely different species that looks similar to C. julii. Later, the “Nanay” was sometimes assigned […]

  • Cherax wagenknechtae (= Red Brick)

    1. March 2023

    The colorful New Guinea crayfish of the genus Cherax have revolutionized aquaristics in some ways. Before their aquaristic discovery in the late 1990s, large crayfish in the aquarium were more a matter for specialists. They were considered formidable plant destroyers, tireless burrowers, and at night they would eat sleeping fish. These are all attributes, with […]

  • Vieja breidohri

    24. February 2023

    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, […]

  • Cryptoheros myrnae “Rio Sarapiqui”.

    24. February 2023

    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 – […]

  • Betta splendens – real fighter Pla Kat Luk Maw

    22. February 2023

    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 […]

  • Pseudeutropius moolenburghae

    20. February 2023

    From Indonesia we received the interesting catfish Pseudeutropius moolenburghae. This shoaling fish, which grows to a maximum length of 10 cm, is very similar in behavior to the well-known glass catfish Kryptopterus vitreolus (formerly known as K. bicirrhis), but is slimmer, livelier and above all has eight long barbels, while the glass catfish has only […]

  • Micropoecilia picta “Trinidad“

    17. February 2023

    From the only very rarely offered species Micropoecilia picta we can offer besides the attractive orange-red variant from Surinam (https://www.aquariumglaser.de/en/fish-archives/micropoecilia-picta-red-surinam-2/) also a second locality variant, namely from the island Trinidad.  Perhaps this form may seem less attractive than the red cousins at first sight. But these little jack-of-all-trades more than make up for it with […]

  • Aphyoditeinae gen. sp. Morse tetra

    17. February 2023

    The unusual term “Aphyoditeinae” is a collective term for small-sized tetra genera in the form of a subfamily, which could not be reasonably placed anywhere else. The world-renowned tetra specialist Jaques Géry introduced the term in 1972 in reference to the genus Aphyodite, but not as a subgenus, but as a vaguely defined term Aphyoditeini. […]

  • Pseudomugil gertrudae

    15. February 2023

    This cute blue eye belongs to our standard offer; the animals are bred ones from Indonesia. Recently we received some very nice specimens. This “no name” variant stays a bit smaller (around 3 cm) than the popular variant from the Aru Islands (https://www.aquariumglaser.de/en/fish-archives/pseudomugil-gertrudae-aru-ii-xl-2/), which reaches almost 4 cm length. Pseudomugil gertrudae has a relatively wide […]

  • Carnegiella strigata lg-xlg

    13. February 2023

    The marble hatchetfish (Carnegiella strigata) is a very common, small-bodied surface fish in the wild. Its maximum length is about 4.5 cm. A very dark form (“vesca”) comes from the upper Amazon (Peru) , a lighter, more delicately marked one from the middle Amazon (Brazil). For “vesca” see here: https://www.aquariumglaser.de/en/fish-archives/carnegiella-strigata-vesca-2/ From Brazil we have just […]

  • Betta strohi

    10. February 2023

    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 […]

  • Pachypanchax playfairii

    10. February 2023

    The Seychelles archipelago off East Africa in the Indian Ocean is known mainly for the giant tortoises that live there. There are hardly any freshwater fish in the Seychelles, most of the freshwater species were brought there by man as food fish. The vast majority of the rest – apart from a few gobies – […]

  • Corydoras treitlii

    8. February 2023

    The long-nosed Corydoras treitlii from the lower Amazon – specimens caught for export mostly come from the Belem area – is one of the real rarities in the trade, although the species is one of the longest known armored catfishes. It was scientifically described already in 1906. With over 7 cm maximum length C. treitlii […]

  • Lebiasina cf. multimaculata

    6. February 2023

    For the first time we could import large (10-12 cm), beautiful Lebiasina tetras from Colombia. The species identification is not completely sure. The animals originate from the Choco region in the south of Colombia; from there e.g. the emperor tetras Nematobrycon lacortei and N. palmeri are exported regularly, between which also young individuals of Lebiasina […]

  • Scatophagus argus

    3. February 2023

    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 […]

  • Glossamia aprion

    3. February 2023

    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 […]

  • Xiphophorus meyeri (update)

    3. February 2023

    The Marble Platy (Xiphophorus meyeri) is one of the rarest species on earth. It was known only from a small area in Mexico, where it was found only in very few places. The species is already considered extinct in the wild. As with its close relative, the Monterrey Platy (X. couchianus), it was the increasing […]

  • Poecilia reticulata Guppy Galaxy Koi

    30. January 2023

    A splendid new breed from Sri Lanka are the Guppy Galaxy Koi, in whose males the hereditary red head and tail markings have been combined with the body color of a Snakeskin. They are beautiful, very vital animals! For our customers: the animals have code 418563 on our stocklist. Please note that we only supply […]

  • Panaque sp. L191

    27. January 2023

    The large wood-eating Panaque of the relationship around P. nigrolineatus are fantastic fishes. Juveniles are almost splendidly colored, so also L191, a species which is still not described scientifically. L191 originates from Colombia. According to the available information the native area is the Rio Caguán in Caquetá. Particularly splendid is with young L191 the green […]

  • Apistogramma sp. Amaya

    27. January 2023

    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! […]

  • Corydoras sterbai WILD

    25. January 2023

    The splendid Corydoras sterbai probably knows every aquarist child. As one of the most beautiful corydoras at all it belongs to the standard offer of the pet trade and is bred in large quantities; there is also an albino breeding form, which does not occur in the wild. Wild Corydoras sterbai from the Rio Guaporé […]

  • Labidochromis sp. “Mbamba”

    23. January 2023

    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 […]

  • Symphysodon aequifasciatus “Royal Green Tefé”.

    20. January 2023

    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 […]

  • Sturisomatichthys sp. Colombia II

    20. January 2023

    The whiptail catfishes belong to the popular and well breedable loricariids. For example, the Real Royal Farlowella (Sturisomatichthys festivus) has been in continuous breeding for almost 50 years, wild catches of this species are very rare. For other species, wild catches and offspring coexist in the hobby.  In former times Sturisomatichthys was considered to mainly […]

  • Lamprologus brevis

    16. January 2023

    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 […]

  • Pseudomugil luminatus „Blue“

    13. January 2023

    From Indonesia have received once again Neon Blueeye under the name Pseudomugil paskai. The first Neon Blueeye, the “Red Neon” (P. luminatus), was a sensation (see https://www.aquariumglaser.de/en/fish-archives/pseudomugil_cf_paskai_red_neon_en/) and also the yellow variant is beautiful (see https://www.aquariumglaser.de/en/fish-archives/pseudomugil_cf_paskai_en/). Now we have obtained a third variant, which this time best corresponds to the “real” P. paskai, also a […]

  • Soon available: Rineloricaria aurata

    13. January 2023

    From Paraguay we regularly receive shipments of the small whiptail catfishes of the genus Rineloricaria. No less than 65 species are currently recognized, which makes identification in many cases almost impossible without knowledge of the origin. But in the case of Paraguay, there is a recent revision of the species known from this river system […]

  • Danio nigrofasciatus

    11. January 2023

    The spotted danio (Danio nigrofasciatus) originates from Burma (Pegu and Mulmein) and is a close relative of the zebra danio (Danio rerio), to which it is completely similar in behavior. However, the spotted danio remains somewhat smaller with a maximum total length of 4 cm. The cute schooling fish come from subtropical regions; in winter […]

  • Pimelodus pictus

    9. January 2023

    Among the large antenna catfishes (Pimelodidae) Pimelodus pictus belongs to the dwarfs. Scientifically proven are 11-12 cm length, but in the aquarium, where these fish can become very old, also 25 cm are said to have occurred. In nature these fishes probably do not live longer than 2-3 years, the keeping record in the aquarium […]

  • Parotocinclus bahiensis and P. cearensis

    6. January 2023

    The genus Parotocinclus currently exists in a kind of shadowy existence in aquaristics. In contrast to their cousins of the genus Otocinclus, hardly anyone knows these equally small loricariids, which are, however, equally zealous algae exterminators. We have received from the Northeast region (Região Nordeste), more precisely from the states of Cereá and Bahia of […]

  • Corydoras kanei

    4. January 2023

    This pretty, at most 5 cm long corydoras wandered for many years under different names through the aquariums, until it was finally described in 1997 by Steven Grant as an independent species: Corydoras kanei. Unfortunately the description is flawed by the fact that the type specimens came from the trade and therefore the type locality […]

  • Oranda Red Cap

    3. January 2023

    One of the most popular goldfish breeds is the Oranda Red Cap. Its name is a Japanese corruption of the word for “Dutchman”, because the first Orandas came to Japan via a Dutch trading post in 1800; however, the animals were bred in China. The hood, called “wen” in technical jargon, is – technically speaking […]

  • Glossolepis spec. “Gidomen Village”.

    30. December 2022

    In 2010 this beautiful rainbowfish was discovered on a private expedition in eastern West Papua. It lives there in the Taritatu River (former: Idenburg River). At first it was thought to be a Chilatherina species, but genetic studies rather point to Glossolepis. The species could be brought back alive and propagated in the aquarium. Nowadays […]

  • Craterocephalus stercusmuscarum

    30. December 2022

    Similar to rainbowfishes, hardyheads (Craterocephalus) are exclusive elements of the Australian fauna. That is, they are found only on the Australian continent and offshore islands (including New Guinea) that formed the large landmass called the Sahul during the Ice Age. Craterocephalus have two separate dorsal fins and, like rainbowfishes, belong to the mullet relatives, but […]

  • Schistura cf. quasimodo

    28. December 2022

    A funny name for a funny loach! In 2000, Kottelat assigned it to a loach from Laos when describing it scientifically. Quasimodo was the hunchbacked bell-ringer in a world-famous novel by Victor Hugo. And the loach from Laos has a hump – hence the name. However, the loach from Laos has a second characteristic that […]

  • Dear ornamental fish friends around the world,

    23. December 2022

    an emotional and eventful year 2022 lies behind us. And the coming year 2023 certainly holds many challenges for all of us in view of the world political situation and the still raging pandemic. That’s why this Christmas, even more than usual, we hope that you and your loved ones will be able to find […]

  • Rubricatochromis: a new genus name for the red jewel cichlids

    23. December 2022

    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 […]

  • Hoplocharax goethei

    23. December 2022

    Do you know this tetra? The species is unusual in several respects! First of all there is its strange species name, goethei. Was the species named after our poet prince and universal genius, Johann Wolfgang von Goethe? Unfortunately no. It was dedicated to the controversial eugenicist Charles Matthias Goethe (1875-1966). But that is rather beside […]

  • Corydoras “punctatus” Nanay

    21. December 2022

    There is a saying: “The Internet forgets nothing”. This may be true, but books are even more durable, especially if errors have been printed in them. These are often so stubborn that one could almost despair. This is what happened to a very pretty armored catfish that occurs in huge numbers in the tri-border area […]

  • Brachyhypopomus brevirostris

    19. December 2022

    Knifefishes are found in Africa, Asia, and South America, with Old World and New World species not closely related. As aquarium fishes, knifefishes are particularly attractive because their elegant swimming style, created by the long anal fin extending over the belly and tail, is fascinating to watch. Like ghosts, the animals glide forward as well […]

  • Tetranematichthys wallacei

    16. December 2022

    At present three species of the strange genus Tetranematichthys are distinguished. None of them comes more frequently or even regularly into the trade, because their hidden way of life makes their catch a pure matter of luck. So we were particularly pleased to be able to import the species T. wallacei from Colombia. We are […]

  • Datnioides polota

    16. December 2022

    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 […]

  • Channa marulius

    12. December 2022

    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 […]

  • Ancistrus sp. Bushmouth LDA 72

    9. December 2022

    Ancistrus species belonged to aquaristics long before one even thought of the term L or LDA number. Unfortunately, the systematics of the group is complex, there have been and still are misidentifications and – this is especially unfortunate – the species can apparently often be crossed, so that aquarium hybrids have been created unintentionally. Such […]

  • Schistura cf. balteata

    9. December 2022

    There is a very great number of scientifically described species of Schistura – more than 300. About 200 of them are currently considered as valid. Only very few species have been imported so far as aquarium fishes. One of the most spectacular of them Schistura cf. balteata, a species collected in the region of Ranchaburi. […]

  • Chlamydogobius eremius 

    8. December 2022

    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, […]

  • Symphysodon wild Nanay Green

    5. December 2022

    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 […]

  • Auriglobus modestus

    2. December 2022

    The golden pufferfishes – the genus name Auriglobus means roughly “golden globe“ – are pure freshwater pufferfishes. For a long time it was thought that there was only one species, A. modestus, which was placed in the genus Chonerhinos. Then it was discovered that there are actually five species, darn similar to each other. We […]

  • Corydoras sodalis (incorrect as agassizii).

    30. November 2022

    There are four species of beautiful corydoras, which are practically without exception available as wild collected specimens from Brazil, because even experienced breeders have a hard time with them. In addition, these species occur in masses and can therefore be offered in large numbers and very cheaply, so there is little incentive to breed them. […]

  • Bhavania australis

    28. November 2022

    Along the west coast of India runs a mountain range known as the Western Ghats. There is a hotspot of biodiversity. An unusually large number of species of freshwater fish are endemic there, i.e. only found there and nowhere else in the world. These include the two species of the genus Bhavania, namely B. annandalei […]

  • Astroblepus from Colombia

    25. November 2022

    The L-catfishes or Loricariidae from South America belong to the most popular and most desired catfishes for the aquarium. However, even experienced aquarists have hardly ever had the opportunity to see a living representative of the genus Astroblepus. It is the only genus of the family Astroblepidae, the closest relatives of the Loricariidae, distinguished from […]

  • Blue Dempsey Cichlids

    25. November 2022

    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 […]

  • Horadandia brittani: A Dwarf from India

    23. November 2022

    At the moment we can again offer Horadandia from South India (Kerala). This miniature fish is also known as the dwarf fire rasbora, as they are closely related to the fire rasboras of the genus Rasboroides. Horadandia reach only a length of 1,5-2 cm. For a long time it was believed that there was only […]

  • Cyphocharax multilineatus

    21. November 2022

    This interesting species, which we obtained from Venezuela, belongs to the Curimata-relationship. At the first glimps it reminds one strongly to the well known headstander (Chilodus punctatus), but it can be easily recognized by the black stripe through the eye. Moreover, Cyphocharax swims in a “normal” horizontal way. Cyphocharax feed on Aufwuchs and look the […]

  • Aspidoras raimundi “Ceará”

    18. November 2022

    The representatives of the genus Aspidoras are popularly also called loach armored catfishes, which is quite a good description. Because the animals are slimmer and more scurrying, than one is generally used to from Corydoras. With 25 species recognized so far, the genus is quite species rich. Their identification is difficult for non-specialists, because species […]

  • Paracanthocobitis botia

    18. November 2022

    From India we could import again this pretty loach. With its 5-7 cm final length it is an ideal bottom fish for moderately tempered (16-22°C) community aquariums with fish of this region, like zebra danios (Danio rerio), rosy barbs (Pethia conchonius), dwarf gourami (Colisa lalia) etc.. In nature, all these species are also occasionally found […]

  • Charax cf. michaeli

    16. November 2022

    There is a conspicuous group of tetras in South America, which we will call “humpback tetras”. They have attracted the interest of researchers since the beginning of fish science (ichthyology), but proved to be a very difficult group in terms of their relationship classification. There are three genera of humpback tetras, which can hardly be […]

  • Rhadinocentrus ornatus

    14. November 2022

    An absolute rarity among the rainbowfish relatives is the ornate rainbowfish Rhadinocentrus ornatus. Within the genus Rhadinocentrus there is only one species, of which however several local variants exist. The reasons for the rarity of this fish in the hobby are that it is a subtropical species, so in the long run it needs certain […]

  • Micropoecilia picta Red Surinam

    11. November 2022

    At first sight the Micropoecilia species resemble the Guppy; however, they are not closely related. Nevertheless Micropoecila picta is often called “swamp guppy” in Surinam, because the species is not only very common in general, but also very common in swampy habitats. Now one could think, the care of such fish of slightly disreputable origin […]

  • Biotodoma cupido Peru

    11. November 2022

    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 […]

  • Badis pallidus

    9. November 2022

    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 […]

  • Channa aurantimaculata WILD

    7. November 2022

    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. […]

  • Pseudacanthicus sp. L600

    4. November 2022

    We have received fantastic leopard cactus plecos L600. They are german bred ones. One specimen is as beautiful and flawless as the other! We are extremely enthusiastic about the quality of the animals. They are currently 6-8 cm long. For our customers: the fish have code 26480-L 600-2 on our stocklist. Please note that we […]

  • Sundadanio cf. axelrodi Blue ( = Rasbora sp. aff. axelrodi BLUE)

    4. November 2022

    The tiny dwarfs of the genus Sundadanio were listed in the genus Rasbora until 1999. At that time only one species was known, namely S. axelrodi. Later other species were imported. They were still nameless, but clearly differed in color. Thus, there were blue, green and red Sundadanio. In 2011 the genus was revised and […]

  • Parancistrus sp. Rio Araguaia L56n / LDA46

    2. November 2022

    The genus Parancistrus includes only two scientifically accepted species, the Golden Parancistrus (P. aurantiacus), which was erroneously also assigned L-number 56 (this is incorrect) and P. nudiventris, which was assigned L-numbers 31 and 176; this is a black catfish with very fine white spots. In addition, we know L258 from Rio Iriri, a black catfish […]

  • Neocaridina denticulata Hulk orange

    31. October 2022

    The Hulk is a comic character from the Marvel universe, a strong, green colored fellow with high destructive potential. We assume that the new dwarf shrimp Neocaridina denticulata Hulk orange, which we could now exclusively import from Taiwan for the first time, is called Hulk because of its green main coloration, because you can hardly […]

  • Apistogramma panduro

    28. October 2022

    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 […]

  • Rocio octofasciata

    28. October 2022

    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 […]

  • Hypostomus sertanejo

    26. October 2022

    For the first time we can offer this very nice Hypostomus from the Rio Jaguaribe (Cerea State, Brazil). It is a species that was described scientifically only in 2017, although 19 specimens of this species were found in the scientific collection of the Academy of Natural Sciences of Philadelphia, U.S.A., which had been collected and […]

  • Nannostomus eques Peru

    24. October 2022

    The tetras of the genus Nannostomus, called pencil fish because of their somewhat stiff swimming style reminiscent of traveling zeppelins, have been among the most popular ornamental fish for decades. They are very beautiful, usually peaceful and remain small. Three species swim at an angle with their heads up: Nannostomus eques, N. britzkii and N. […]

  • Colisa lalia now Trichogaster fasciata?!

    21. October 2022

    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 […]

  • Poecilia (Mollienesia) sphenops Marble Ancient

    19. October 2022

    The livebearers are the backbone of aquaristics. The hobby would be unimaginable without Guppy, Platy, Molly and Co. We notice two trends in the breeding of these fish: one deals with the wild forms, which were very rare or not available at all in the trade; and the other develops new, colorful breeding forms, but […]

  • Astronotus sp. NEW ZEBRA/Tapajos

    17. October 2022

    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 […]

  • Curimatopsis evelynae

    14. October 2022

    The tetras of the genus Curimatopsis are widely distributed in South America. The prettiest species is C. evelynae. Nevertheless, this attractive fish has hardly found its way into aquariums so far. C. evelynae grows to a maximum length of 4 cm. The males can be recognized by their clearly higher caudal peduncle, furthermore the females […]

  • Corydoras cf. brevirostris CW 27 Highfin

    12. October 2022

    We received a limited number of this extraordinary Corydoras from Colombia. The overall appearance is very much alike Corydoras brevirostris (formerly known as Corydoras melanistius brevirostris), but CW 27 has a much much higher dorsal fin and the “glowspot” on the nape is much brighter. For our customers: the animals have code 224954 on our […]

  • Apionichthys nattereri

    10. October 2022

    When we think of flatfishes like flounders, plaice, butts and tongues, we actually think of the sea and edible fishes. However, it is little known that several species are also purely freshwater dwellers. Among the Achiridae (American sole) in South America, for example, 26 species are known from freshwater, but many of them are euryhaline, […]

  • Physopyxis lyra

    7. October 2022

    Although this dwarf among the thorny catfishes – it only grows to about 3 cm in length – was scientifically described as early as 1872, it was completely unknown to aquarists until a few years ago. This is a pity, because they are droll, very interesting small catfishes, which are also suitable for small and […]

  • Mogurnda mogurnda

    5. October 2022

    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 […]

  • Crenicichla sp. Tapajos I / Cobra Pike

    30. September 2022

    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 […]

  • Tylomelania towutensis

    30. September 2022

    The snails of the Malili Lakes on Sulawesi (formerly: Celebes) belonging to the family Pachychildae are great animals to keep for their own sake and not just as useful algae and debris eaters, like many other snails. All Tylomelania species of the region have in common that they occur in warm (around 30°C), soft and […]

  • Rasbora einthovenii

    30. September 2022

    A typical companion fish of harlequin barbs (Trigonostigma), chocolate gouramis (Sphaerichthys) and other blackwater fish is Rasbora einthovenii. The species is unfortunately very rarely imported, although it has a large range. It is found on the large Sunda islands of Sumatra and Borneo, on the Malay Peninsula and in southern Thailand in suitable biotopes. Usually […]

  • Thayeria obliqua

    28. September 2022

    Unfortunately the beautiful penguin tetra, Thayeria obliqua, from the upper Amazon is offered only very rarely, in contrast to its cousin T. boehlkei, which can always be found in the trade. In the trade are only offsprings of T. boehlkei; it originates from the Rio Xingu drainage in Brazil. A third species, T. ifati from […]

  • Devario sondhii

    26. September 2022

    This beautiful danio comes from Burma. It looks like the big brother of Microrasbora rubenscens. Males become wonderful red. Temperature: 18-28°, the water should preferably be rather hard and alcalic than soft and acidic, the fish is a peaceful schooling fish that attains a maximum length of around 5-7 cm. For our customers: the fish […]

  • Rineloricaria teffeana

    24. September 2022

    The small remaining whiptail catfishes of the genus Rineloricaria enjoy great popularity among aquarists. They have a whimsical appearance, are peaceful, have no high space requirements and can usually be bred quite well. Some species have even really fancy pattern. The most beautiful is certainly R. teffeana. It has no bright colors, but a really […]

  • Parotocinclus jumbo LDA25, now available as German bred!

    24. September 2022

    The cute Parotocinclus jumbo, also known as Pitbull Pleco or LDA25, is a very popular aquarium fish. Unfortunately imports take place only very irregularly and can hardly be planned. Therefore we are happy to be able to offer this nice little fish as offspring now. More information about the species can be found here: https://www.aquariumglaser.de/en/fish-archives/lda25-parotocinclus-jumbo-2/ […]

  • Parambassis lala Bred

    21. September 2022

    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 […]

  • Hara hara/Erethistes pusillus

    19. September 2022

    In India live two species of moth catfishes, which are practically impossible to distinguish in living condition. They are nevertheless sometimes even assigned to two different genera: Hara and Erethistes. The difference between the two genera lies in the structure of the vertebral body, that is, of something invisible in the living animal; according to […]

  • Lamprichthys tanganicanus

    16. September 2022

    With a maximum length of 14 cm, the Tanganyika lampeye fish is the largest lampeye fish at all. It is found exclusively (= endemic) in Lake Tanganyika, where it lives in huge schools along rocky coasts. It is a breathtaking sight when such a shoal, comprising several thousand individuals, comes swimming around a cape like […]

  • Aphyosemion (Chromaphyosemion) bivittatum “Funge”.

    16. September 2022

    The Funge is a river or, rather, estuary in southeastern Cameroon in the district of Ndian. The Funge is less than 40 km long and is part of a system of coastal marshlands whose best known outlet is the Rio del Rey. This in turn is in contact with the Cross River drainage, which forms […]

  • Mugilogobius chulae

    14. September 2022

    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 […]

  • Mugilogobius mertoni

    14. September 2022

    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 […]

  • Poecilia (Mollienesia) sphenops RED

    9. September 2022

    The breeders in Southeast Asia have realized a new color variation of the good old Black Molly, which they call “Red”. This is not a solid red fish, like for example a red swordtail, but the breeding form “Red” of the Molly has red spots in different intensity on the scales. When viewed from above, […]

  • Vitta virginea ( = Neritina virginea)

    9. September 2022

    The Nerites, also known as racing snails (family Neritidae), are distributed worldwide in warm and temperate zones. They have an operculum at the foot that allows them to close the shell completely, a cup-shaped shell, and they are often strikingly brightly colored. Many tropical species colonize uppermost shore areas and can live in both seawater […]

  • Pandaka rouxi

    7. September 2022

    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, […]

  • Lepisosteus oculatus “Metallic“

    5. September 2022

    We have already reported about the Spotted Gar (Lepisosteus oculatus), see https://www.aquariumglaser.de/en/fish-archives/lepisosteus-oculatus-2/. Now we have received small gars from Indonesia, which correspond in all characteristics to L. oculatus, but show a very striking silver luster. The smaller ones (6-8 cm) have a quite dark basic coloration, which brightens up clearly with somewhat larger animals (11-14 […]

  • Corydoras leucomelas

    2. September 2022

    Corydoras leucomelas belongs to the frequently imported species of its genus. Typical characteristics of the round-nosed species are a strongly pronounced eye band, the coloration of the dorsal fin in connection with the black dorsal spot located at the beginning of the dorsal fin, a vertical black band at the end of the caudal peduncle […]

  • Pyrrhulina spilota

    2. September 2022

    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 […]

  • Symphysodon “Super Red Turqoise”.

    31. August 2022

    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 […]
