  • Nanochromis cf. teugelsi

    17. January 2022

    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 […]

  • Pao sp. Chao Phraya

    14. January 2022

    The cockade pufferfishes are a very complex group of freshwater pufferfishes. Formerly they were called the “Tetraodon-leiurus group”, but since 2013 they are in the genus Pao. The genus name Tetraodon is now only applied to the freshwater puffers of Africa. Throughout Southeast Asia (Thailand, Laos, Cambodia, Vietnam, Malaysia, Singapore, Indonesia), Pao freshwater puffers can […]

  • The sturgeon catfishes of Paraguay: Sturisoma barbatum or S. robustum?

    14. January 2022

    From Paraguay wonderful, partly very large sturgeon catfishes (Sturisoma) are imported. Two Sturisoma species are known from the Rio Paraguay: S. barbatum, described already in 1853 by Kner, and S. robustum, described in 1904 by Regan. The two species differ from each other only insignificantly.  The most important anatomical feature distinguishing the two species is […]

  • Pethia gelius

    12. January 2022

    The golden barb (Pethia gelius) is an aquarium old-timer that found friends even before the First World War. It is one of the smallest barb species in India. Males rarely grow longer than 2.5 cm, females slightly larger. The record of 5 cm total length, which has been haunting the literature for decades, is probably […]

  • Channa stewartii

    10. January 2022

    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 […]

  • Hypseleotris compressa

    7. January 2022

    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 […]

  • Baryancistrus sp. Snowflake LDA 33 / L142

    7. January 2022

    This beautiful loricariid catfish comes from the Rio Tapajós in Brazil. Usually, 4-5 cm long youngsters are imported from these catfishes, which look very attractive with their large, white dots on a deep black ground and fully deserve the name “Snowball-Pleco”. In addition to high water temperatures (not below 28°C), these catfishes should be kept […]

  • Xiphophorus hellerii “Jalapa”

    5. January 2022

    When you first see this slender, splendidly colored swordtail wild form, you involuntarily think: this is no X. hellerii! And yet, when X. hellerii was first described in 1848, exactly such animals became the type specimens. The traveler of the royal imperial horticultural society Karl Heller discovered and collected the animals in clear streams of […]

  • Sartor respectus

    4. January 2022

    From the Rio Xingu we could import the probably strangest of all headstander: Sartor respectus. Unfortunately there were only two specimens, which one of our employees acquired. Nevertheless we did not want to withhold this speciality from you, dear readers.  Sartor (there are two other very similar species, one from the Rio Trombetas (S. elongatus) […]

  • The “real” Corydoras melini?

    31. December 2021

    One of the most important arguments for importing wild-caught fish for aquaristics is the gain in knowledge it allows. For the majority of small fish species this is only possible by observing living specimens. Without this there is no species knowledge, without species knowledge there is no species conservation. A wonderful example of the above […]

  • Xenopus tropicalis

    29. December 2021

    Most likely, the trade of clawed frogs of the species Xenopus laevis will soon be banned because a reproducing population has been discovered in France. Due to climate change, it is now feared that this species could become invasive in Europe. To prevent this, the trade with this species should be prohibited. We would like […]

  • Mayaheros beani (formerly: Cichlasoma b.)

    28. December 2021

    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 […]

  • Acanthopsoides robertsi

    24. December 2021

    Horseface loaches (Acantopsis) are popular and well-known aquarium fishes, but with 15-20 cm attainable final length (the record is even 25 cm) they become quite large and therefore need larger aquariums. Practically unknown to aquarists are the dwarf horseface loaches (Acanthopsoides), whose seven species grow to only 3.5-5.5 cm in length. The photographed specimens are […]

  • Desmopuntius rhomboocellatus

    24. December 2021

    Once again we have been able to import beautiful, fully grown specimens of the Orange Barb; unfortunately they are already sold out, but we want to use this opportunity to point out another of the numerous name changes of the Asian small barbs. Desmopuntius – the name means “convict barb” and refers to the striped […]

  • Polypterus mokelembembe

    22. December 2021

    Bichirs are so called living fossils. Already 60 million years old fossils were found, which can still be assigned to living species today. However, there are only 16 known species, all coming from Africa. The last discovered and at the same time smallest species of the genus is Polypterus mokelembembe, which was described as a […]

  • Xiphophorus nezahualcoyotl

    20. December 2021

    We have just obtained very attractive offspring of the “Northern Mountain Swordtail”. The fish are young adults, i.e. the sword of the males is still relatively short. For comparison we show here also an adult pair of another strain. In former times X. nezahualcoyotl was considered as a local variant of X. montezumae. The name […]

  • The global ornamental fish trade in times of Corona

    17. December 2021

    The ornamental fish industry, as an international, global player, is naturally particularly affected by the pandemic; however, it is not only the virus and its direct effects that are causing problems for breeders, catchers and exporters around the world. Climatic changes, industrial conversion of the landscape, water pollution and social aspects also have a major […]

  • Steatocranus gibbiceps

    15. December 2021

    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 […]

  • Andinoacara latifrons Rio Atrato

    13. December 2021

    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 […]

  • Tetraodon schoutedeni

    10. December 2021

    In the 1960s Tetraodon schoutedeni was one of the most common freshwater puffers in the trade. Also the breeding of the animals succeeded regularly. The fish are free spawners without brood care. But the civil war in Congo changed the situation drastically and even nowadays catchers are reluctant to go to the occurrence areas of […]

  • Pao abei (formerly: Tetraodon or Monotrete abei)

    10. December 2021

    In Southeast Asia a group of freshwater puffers exists that is extremely difficult to tell apart on a specific level. They are called the Eyespot-Puffers or the Pao-leiurus-complex. These puffers live in streams and rivers, some also in ponds and lakes, always in pure freshwater. Among the most enigmatic species is Pao abei, which has […]

  • Hyphessobrycon moniliger

    9. December 2021

    Under the name “Hasemania hansseni” a new tetra has recently appeared on the market, which with its intense orange coloration is indeed somewhat reminiscent of the well-known copper tetra, Hasamania nana. However, one of the characteristics of the genus Hasemania is that it lacks the adipose fin that is so typical for tetras. This is […]

  • Poecilia wingei Campoma No31 Snake Blue

    6. December 2021

    Infinite is the variety of colors, patterns and color combinations possible in wild guppys. In natural biotopes no two males are alike. There are multiple mechanisms, genetic and biological, that ensure this. This is also true for the two wild guppy populations assigned to the species Poecilia wingei: Campoma and Cuminá. However, if individual males […]

  • Corydoras geoffroy

    3. December 2021

    For a long time this fish, the type species of the genus Corydoras, was a mystery. Until today it is a top rarity among the armored catfishes. And so we are especially pleased to be able to offer offspring of this precious fish once again. The animals are still a bit inconspicuous, so we would […]

  • Filigran Guppys – King Cobra Guppys

    3. December 2021

    The Filigran Guppys belong to the most popular Guppy forms. They have a body pattern of squiggles and dots, which is also called “Snakeskin” or King Cobra. This body pattern sometimes appears in wild Guppys, but it was not until the 1950s that it received more attention and was genetically characterized by M. Dzwillo in […]

  • Hypselecara temporalis OYAPOC

    1. December 2021

    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 […]

  • Glyptoperichthys gibbiceps

    29. November 2021

    The red highfin sucker is a classic, which found its lovers long before the invention of the L-numbers. Juveniles are really adorable and excellent algae killers. In addition they look very beautiful. Since this catfish easily grows to 30-40 cm in length, there are two camps among aquarists. Some are critical of the animal because […]

  • Mikrogeophagus ramirezi “Black”

    26. November 2021

    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 […]

  • Corydoras undulatus Paraguay

    26. November 2021

    The beautiful Corydoras undulatus belongs to the relationship of C. elegans. Like most representatives of this group the species swims rather in free water than on the ground. Also typical for the group is that males and females differ clearly in color. In the case of C. undulatus the males become very dark with bright […]

  • Rineloricaria parva

    25. November 2021

    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 their origin. But in the case of Paraguay, there is a recent revision of the species known from this river system […]

  • Ancistrus Orange Brown “LDA16”

    22. November 2021

    This extremely attractive Ancistrus is a breeding form. The actual LDA 16 is a wild form imported in 1994 from Brazil (Rio Puraqequara, a tributary of the Rio Guamá, which in turn is a tributary of the Rio Tocantins) and is uniformly purple-brown in color. We do not know if the orange-blotched Ancistrus descended from […]

  • Pangio cuneovirgata

    19. November 2021

    Usually the different species of banded Coolie loaches (Pangio kuhlii, P. semicincta, P. myersi, P. shelfordi, P. alternans, P. cuneovirgata, P. malayana) are not distinguished in the trade because they are so variable in color and are often imported mixed. The sorting of Coolie loach is an activity you don’t want your worst enemy to […]

  • Hypostomus roseopunctatus L311

    19. November 2021

    Not less than 148 species are counted to the genus Hypostomus, but no five of them appear more often in the trade. Special is of course H. luteus with its sail-like dorsal fin and the bright yellow coloration, but most species are “plecos”, brown or gray with black spots. In addition, most species grow quite […]

  • Geophagus harreri

    17. November 2021

    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 […]

  • Characidium fasciatum (C. cf. pterostictum, P. sp. V)

    15. November 2021

    The South American darters of the genus Characidium are unfortunately almost indeterminable. There is no current revision of the 95 described species, but additional species are constantly being described and it is known that there are still numerous scientifically unrecorded species. In aquaristics one therefore helps oneself by simply calling everything “Characidium fasciatum”, well knowing […]

  • Heros sp. Madeira

    12. November 2021

    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 […]

  • Pseudacanthicus sp. L273 Titanic

    12. November 2021

    The magnificent cactus catfish L273 Titanic, up to 30 cm long, originates from the Rio Tapajós. Its first import in 1998 was a sensation. Interesting about the animals, which are allowed to be exported from Brazil again since some time, is the very individual body pattern. All cactus catfishes are carnivores; towards non-species fishes they […]

  • Zungaro zungaro

    10. November 2021

    The catfish Zungaro zungaro belongs to the largest catfish species of South America. There were all kinds of debates about its name, for a long time it sailed under Pseudopimelodus zungaro or Paulicea luetkeni. Because of its gigantic size (length up to 140 cm, weight up to 50 kg) the species is difficult to study […]

  • Crenicichla jegui

    8. November 2021

    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 […]

  • Girardinus uninotatus

    5. November 2021

    From the currently seven accepted species of the genus Giradinus only G. metallicus and occasionally G. falcatus are offered in the trade. We have now received a small number of G. uninotatus from a breeder. They are really no color miracle, but their pretty apricot color is quite interesting. The species oirginates from Cuba. The […]

  • Cochliodon sp. L360

    5. November 2021

    We have received some beautifully marked yellowseam catfish. This catfish originates from the middle Rio Jamanxin in Brazil and has not yet been correctly (i.e. scientifically) identified, neither in terms of genus nor in terms of species. However, it is quite possible that this catfish has already been scientifically described; young animals are quite inconspicuous, […]

  • Macropodus spechti “Royal Blue”

    3. November 2021

    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 […]

  • Scleromystax barbatus

    1. November 2021

    The changed legal situation in Brazil now makes the import of several species from the south of Brazil possible again, which for many years were only available as offspring, among them the magnificent Scleromystax barbatus (formerly Corydoras b.). We have been able to import a good number of wonderful, fully grown specimens. For more information […]

  • Biotoecus dicentrarchus

    29. October 2021

    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 […]

  • Pterophyllum leopoldi (“dumerilii”)

    29. October 2021

    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 […]

  • Serrasalmus cf. gouldingi

    27. October 2021

    It is indicative of the difficulties in piranha identification that this widespread species, which also occurs in an area intensively collected for the aquarium hobby (namely, the Rio Negro) was not scientifically described until 1992 and, moreover, almost never appears in the hobby. The terra typica is Anavilhanas, Río Negro, Brazil.  The representatives of this […]

  • L350 Panaque sp. Black Lyretail

    25. October 2021

    From Peru we received four specimens of a top rarity: L350. This peculiar fish does not fit any genus of loricariid catfish known to date. It originates from deep, turbid, very fast flowing water of the Peruvian Amazon, where it can only be caught with great difficulty and rarely. It is a carnivorous species whose […]

  • Scleromystax barbatus

    22. October 2021

    The changed legal situation in Brazil now makes the import of several species from the south of Brazil possible again, which for many years were only available as offspring, among them the magnificent Scleromystax barbatus (formerly Corydoras b.). We have been able to import a good number of wonderful, fully grown specimens. For more information […]

  • Moenkhausia phaeonota

    22. October 2021

    This small (about 4 cm) species of tetra originates from upper Rio Tapajós basin the Mato Grosso state in Brazil. It is the only species of Moenkhausia with such a colour pattern. So already in the original scientific description (1979) the author mentioned that this generic placement can be only provisionally. This makeshift stands until […]

  • Colisa lalia “Flame Red

    18. October 2021

    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 […]

  • Acestrorhynchus cf. minimus

    15. October 2021

    Unfortunately, almost all predatory fishes have one unpleasant characteristic: most of them grow too large for average aquarium dimensions. In many cases we can only keep juveniles for some time and have to part with them when it becomes nice. What a pity! An exception to this rule is Acestrorhynchus minimus, a barracuda tetra from […]

  • Corydoras eversi (C65)

    15. October 2021

    The very nice Corydoras eversi lives in the Araguaia drainage (Brazil) and became known as C 65. It was only scientifically described in 2016. The scientific treatment of C. eversi is based on a collection by Hans-Georg Evers in 1998, who was also able to bring living animals with him. As mentioned, they were initially […]

  • Apareiodon affinis

    13. October 2021

    Now begins the season for one of the best algae eaters of all, the La Plata algae eater from Paraguay. Originally the species was described as Parodon affinis. It is amazingly similar in shape and coloration to the Asian Flying Foxes; but of course, the La Plata algae eater can always be easily recognized by […]

  • Poecilia mexicana “Campeche”

    8. October 2021

    The wild mollies are – from a zoological-systematic point of view – certainly one of the most difficult fish groups at all. Not without reason, science has been wavering between two extreme views for over 100 years: the first states that all wild mollies belong to only one, highly variable species, which would then be […]

  • Guppy Endler

    8. October 2021

    No fish species is as changeable as the Guppy. There are no two males in nature that are exactly alike in color. This is true for all four Guppy species (Poecilia reticilata, P. wingei, P. obscura and P. kempkesi), which therefore cannot really be distinguished from each other externally (genetically, however, they can). In the […]

  • Coryoras eques

    7. October 2021

    From the Brazilian state of Amazonas, more precisely from the surroundings of the city of Anori, we once again received a good number of a beautiful armored catfish, which is known to science for a long time, but rarely appears aquaristically: Corydoras eques.  This typical schooling Corydoras looks most attractive when kept in black water. […]

  • Atractosteus spatula

    5. October 2021

    The Alligator gars are so-called living fossils. They developed about 100 million years ago in the upper Cretaceous and haven´t  changed much since then. Currently two genera live in the New World, namely Atractosteus (containing three species) and Lepisosteus (four species). The members of Atractosteus can reach about 2 m in length (formerly they are […]

  • Procatopus aberrans

    1. October 2021

    Again we could import the lampeye fish Procatopus aberrans from NIgeria; unfortunately we do not know the location where they were collected. However, we know that our supplier occasionally receives fish from Cameroon. Anyway, the current imports are a bit more graceful in body structure and the upper half of the iris lacks the red […]

  • Bedotia geayi

    1. October 2021

    This is the only almost always available aquarium fish that comes from the large, geologically old island of Madagascar. All other freshwater fishes from this island, which unfortunately are often threatened with extinction due to massive environmental changes, are only suitable for specialists.  The beautiful Madagascar rainbow (Bedotia geayi) grows to a length of 10-12 […]

  • Guppy Japan Blue and Japan Red

    24. September 2021

    There is a number of tail fin shapes of the guppy, which have been standardized by the guppy breeders. As a rule, however, these breeds are only found at private breeders. In the pet trade the triangle guppies dominate in such a way that aquarists, who do not inform themselves specifically about guppies, could get […]

  • Xiphophorus signum

    24. September 2021

    This species of swordtail is only very rarely offered in the trade. At the first glimpse one may think that they are a variety of the common swortail X. hellerii, but the species X. signum is much more slender. The mark that is responsible for the scientific name (latin signum = sign) is always good […]

  • Colomesus asellus

    22. September 2021

    The South American puffer fish Colomesus asellus are ideal for aquarium care. They remain small (usually around 6-8 cm, at most around 12 cm, other sizes given in the literature are based on confusion), are pure freshwater inhabitants, love to eat small snails and are absolutely peaceful, both against conspecifics and against other fish species. […]

  • Spectracanthicus (= Oligancistrus) zuanoni L 354

    20. September 2021

    Spectracanthicus zuanoni L 354 originates from Rio Xingu and the Rio Iriri in Brazil. It has been described scientifically only in 2014 (see http://www.aquariumglaser.de/en/archiv.php?news_id=1195). The fish belongs to the same species as L 20, with however clearly larger white marks, so that the design reminds of a black net on a bright background. The reddish, […]

  • Pimelodus ornatus

    17. September 2021

    One of the most attractive large catfishes is Pimelodus ornatus, which is common in large parts of tropical South America. It is reported from the big rivers Amazonas, Orinoco and Parnaná, in addition the Guyana states. Maximum size reported is 38.5 cm (excluding caudal fin). The beautiful and lively fish is notorious for its venomous […]

  • Corydoras loxozonus and C. sp. aff. C16

    17. September 2021

    Corydoras loxozonus belongs to the beautiful armored catfishes, which we receive relatively regularly from Colombia. The species is quite variable in pattern and therefore has already received the C-numbers C79 and C83. There was never any “proof” that these C-numbers really belong to the species C. loxozonus; this was only concluded from the fact that […]

  • Botia lohachata

    15. September 2021

    The systematics of the Indian deep bodied loaches – they represent the remaining species in the formerly much broader genus Botia – is confused. Botia lohachata was described from Bihar in India as early as 1912. Their coloration is very specific: three Y-shaped bands – the first in front, the second below and the third […]

  • Nannacara taenia

    10. September 2021

    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 […]

  • Chindongo socolofi (= Pseudotropheus s.)

    8. September 2021

    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 […]

  • Xenomystus nigri

    6. September 2021

    Knifefishes are found in the Old World (Africa, Asia) and in the New World (South and Central America). However, the two groups are not closely related. Aquaristically, however, they are quite comparable. They inspire above all by their elegant swimming. The very special fin structure allows them to maneuver both forward and backward. At the […]

  • Periophthalmus novemradiatus

    3. September 2021

    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: […]

  • Curculionichthys sabaji

    1. September 2021

    A very long name for a very small fish! The genus Curculionichthys was established only in 2015 to accommodate dwarf sucker catfishes of the subfamily Hypoptopomatinae (formerly: Otothyrinae) of Loricariidae, which were previously placed in the genus Hisonotus. Both anatomical and molecular data showed that two independent evolutionary lineages existed within Hisonotus, namely that around […]

  • Ancistrini sp. L82

    30. August 2021

    Among the species threatened by the construction of the Bela Monte Dam is L82, a species of loricariid up to about 15 cm long, which cannot yet be assigned to any genus described scientifically to date; it is most similar to Scobinancistrus. Also on species level L82 is not yet worked on. The only certainty […]

  • Abramites hypselonotus

    27. August 2021

    The marbled headstander is perhaps the most unusual of all headstanders. This beautiful fish grows to about 15-20 cm in length and is hard to mistake because of its high body shape. There is only a second Abramites species, A. eques, but it has never been imported alive. It lives exclusively in the Rio Magdalena […]

  • Pseudacanthicus sp. L79

    27. August 2021

    This very flat Pseudacanthicus from the Rio Tocantins belongs to the rarest L-catfishes on the market. Even before the export ban by the Brazilian authority IBAMA, which was lifted only recently, the fish came to us only very sporadically. L79 certainly grows over 20 cm long, but exactly how big is unknown. Our animals are […]

  • Poecilia wingei Blue Star

    25. August 2021

    Poecilia wingei is widely distributed in the hobby after its best known local variant as Endler´s Guppy. It remains much smaller than the normal Guppy and is very popular with many aquarists because of its graceful body shape.  Just as with the common Guppy, numerous local forms can be observed with P. wingei. The ancestor […]

  • Sciaenochromis fryeri

    23. August 2021

    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 […]

  • Ageneiosus magoi

    20. August 2021

    Males of all dolphin catfishes (Ageneiosus) develop huge dorsal fin spines and a penis-like mating organ at spawning time, also strange tooth-like looking papillae on the posterior margin of the upper jaw. They use the dorsal fin spine to clamp females for mating, and fertilization occurs internally. After spawning, the dorsal fin spine is shed […]

  • Wertheimeria maculata

    20. August 2021

    Wertheimeria maculata belongs to the strangest thorny catfishes. You don’t see this on the relatively inconspicuous juveniles with their 6-8 cm length, but it is nevertheless so. The first thing that catches your attention is the really high price that is demanded for them. This is due to the fact that these fish are local […]

  • Mylesinus paucisquamatus

    19. August 2021

    A few weeks ago we introduced you to a new pacu, which we received as Tometes kranponhah. At that time we thought the animals originated from the Rio Xingu. (see https://www.aquariumglaser.de/en/fish-archives/tometes-kranponhah-2/)  In the meantime, further correspondence with our supplier revealed that the animals did indeed come from the Rio Tocantins. We have received another shipment […]

  • Platy Wagtail Pointed Tail

    16. August 2021

    The “pointed tail” mutation, in which the middle caudal fin rays are elongated, appeared relatively late: the first specimens appeared on the market in the 1980s. It originated in the Southeast Asian large-scale breederies. The characteristic, which first appeared in the Platy (Xiphophorus maculatus), can also be transferred to other Xiphos, but the pointed tail […]

  • Acanthicus sp. L155 Furo Maguari

    13. August 2021

    Acanthicus hystrix is one of the great myths in the literal sense. With a length of almost one meter it is one of the largest loricariid catfishes at all. In addition, the species, which was already described in 1829, is extremely prickly: “hystrix” means “porcupine”!  Unfortunately, the specimen on which the description of this species […]

  • Aulonocara Orange Blotched

    12. August 2021

    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 […]

  • Amatitlania (formerly Cichlasoma) nigrofasciata Marble

    9. August 2021

    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 […]

  • Betta splendens Hellboy II

    6. August 2021

    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 […]

  • Guppy Kohaku Koi Tuxedo

    6. August 2021

    Guppy breeders are currently very active again and bring new, attractive strains on the market. The Guppy Kohaku Koi Tuxedo combines two special characteristics: The Kohaku factor, which causes males and females to have a red head combined with a red caudal fin and red dorsum; and the Elephant Ear factor, which causes the greatly […]

  • Paracheirodon simulans

    5. August 2021

    Paracheirodon simulans is the smallest and tiniest species of neon tetra. The maximum length is around 2.5 cm. One should not confuse this species with the neon costello, Hemigrammus hyanuary, which is also called the “green neon” occasionally. This is the reason why some people call Paracheirodon simulans the “blue neon”, but in the international […]

  • Alestopetersius leopoldianus

    30. July 2021

    Our current Congo import contained among others the magnificent tetra Alestopetersius leopoldianus, which originates from Lac Mai Ndombe (formerly: Lake Leopold) and the middle Congo. With this maximum 9 cm long species one can get philosophical about the supposed objectivity of photography. Depending on the incidence of light the animal looks completely different! With the […]

  • Corydoras elegans C123

    30. July 2021

    The beautiful Corydoras elegans is widely distributed in the Amazon region and locally forms numerous color forms. Possibly all these variants are even independent species, but scientifically this has not been investigated yet. A color variant from the Rio Nanay in Peru stands out above all by yellow-orange tinted fins. Some males (they have higher […]

  • Nanochromis parilus wild

    28. July 2021

    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 […]

  • Moenkhausia nigromarginata

    23. July 2021

    Again we can announce a first import: Moenkhausia nigromarginata. For the first time ever we received some of these tetras described in 1994. The species reaches a length of about 5 cm. Striking are the blue eye, the blue back in incident light and the – sometimes more and sometimes less visible – zigzag bands […]

  • Crenicichla from the Rio Xingu

    21. July 2021

    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 […]

  • Hyphessobrycon moniliger

    19. July 2021

    Under the name “Hasemania hansseni” a new tetra has recently appeared on the market, which with its intense orange coloration is indeed somewhat reminiscent of the well-known copper tetra, Hasemania nana. However, one of the characteristics of the genus Hasemania is that it lacks the adipose fin that is so typical for tetras. This is […]

  • Moenkhausia rubra

    16. July 2021

    New legislation in Brazil now allows the import of species whose export was previously not allowed. One of these species is Moenkhausia rubra, which was only scientifically described in 2014. The species is so far known only from the Rio Juína and the Rio Juruena, both belonging to the upper Rio Tapajós drainage, Mato Grosso […]

  • Coyrdoras paleatus wild

    16. July 2021

    Only very rarely we receive wild collected Corydoras paleatus. Imports of this species, which is widespread in southern South America, didn´t appear for more than 10 years, because many export stations in southern Brazil had to close down when some of the most important ornamental fishes of the region were forgotten on the Brazilian positive […]

  • Anabas testudineus

    14. July 2021

    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. […]

  • LDA25 Parotocinclus jumbo

    12. July 2021

    The Pitbull Pleco (Parotocinclus jumbo, formerly Hypostominae gen. sp.) was one of the most popular small sucking catfishes until about 10 years ago. Then it was accidentally forgotten on the list of Brazilian ornamental fishes allowed for export. Since then, it has only been around in breeder circles. This species, very common in the wild, […]

  • Guppy Neon Green Lyretail

    9. July 2021

    Aquaristics is unimaginable without the multitude of colorful livebearer breeding forms. However, this also means that there is competition between the different breeding lines for the buyers’ favor. A good name clearly sells. And even if, strictly speaking, the Neon Green Lyretail is neither neon green in color nor has a lyre tail – who […]

  • Hyphessobrycon sp. “Muzel Red Cherry“

    7. July 2021

    From Brazil we received this really nice novelty, which looks a bit like an enlarged edition of the Ember tetra, Hyphessobrycon amandae. However has the “Muzel Red Cherry” two (although indistinct) shoulder spots, which never occurs in H. amandae.  In addition, the dorsal fin in “Muzel Red Cherry” is red with a light margin, while […]

  • Melanotaenia praecox

    6. July 2021

    The Diamond Rainbowfish – Melanotaenia praecox – is one of the smallest species of the actual rainbowfishes and grows only 6-7 cm long. It shows already from 3 cm length its splendid iridescent body coloration. That is why it is one of the most popular species in the trade. With age the males become high-backed […]

  • Aulonocara “Dragon Blood”

    2. July 2021

    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. […]
