07. Carp like fishes (1): Loaches (93)

  • Misgurnus anguillicaudatus GOLD

    10. January 2024

    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 […]

  • Leptobotia tchangi

    2. January 2024

    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 […]

  • Beaufortia kweichowensis

    1. December 2023

    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 […]

  • Schistura atarensis ( = Schistura cf. balteata)

    17. November 2023

    There are a large number – over 300, of which over 200 are considered valid species – of scientifically described Schistura species; only very few of these have found their way into aquaria to date. One of the most beautiful is the species previously known as Schistura cf. balteata from Thailand, which was recently (October […]

  • Botia rostrata

    1. November 2023

    To say it right away: nobody knows exactly which species of loach is hidden behind the name Botia rostrata from a scientific point of view. But this is not the right place to discuss such things. Especially interested people are referred to the very detailed work of Steven Grant (2007). The loach we present here […]

  • Gastromyzon “punctulatus”

    18. August 2023

    In 1961, a review paper on the hillstream loaches of the genus Gastromyzon of Borneo was published. In it five species were distinguished: G. pauciradiatus, G. nieuwenhuisii, G. fasciatus, G. punctulatus and G. borneensis. In 2006 the next revision of these fishes from Borneo appeared. This was accompanied by a true species explosion; in Gastromyzon […]

  • Annamia sp. (= Vanmanenia sp.) Vietnam

    21. April 2023

    From time to time we receive the beautiful, large hillstream loaches Annamia normani (see https://www.aquariumglaser.de/en/fish-archives/annamia_normani_en/) from Vietnam. Recently we received again a shipment of very similar specimens, but they differ clearly from the A. normani we know well by the very contrasting tail fin. Since all specimens (over 50) show this feature, it cannot be […]

  • Petruichthys  brevis (formerly: Yunnanilus brevis)

    14. April 2023

    Petruichthys brevis is a species of loach that originates from Burma. Here it occurs only in Inle Lake. The species attains a length of only 4-5 cm and thus belongs to the small species of fish. In contrast to most other species of loach, this one is a free swimming, schooling species. The swimming behaviour […]

  • 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 […]

  • 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. […]

  • 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 […]

  • 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 […]

  • Botia kubotai

    27. May 2022

    Some botias, among them B. kubotai, are available only seasonal and for a quite short time per year. The very beautiful species B. kubotai originates from the Salween-tributary Ataran in the border region between Burma and Thailand. It becomes around 8-10 cm long, maximum length reported so far is 13 cm. This species is one […]

  • Yasuhikotakia modesta (2)

    22. April 2022

    One of the most beautiful and largest botias besides the well known and popular Chromobotia macracanthus is the Redtail botia Yasuhikotakia (formerly: Botia) modesta from Southeast Asia. These are gorgeous fish, usually with a very unusual dove blue base coloration that contrasts very nicely with the red fins. But there are also green, yellow-finned variants […]

  • Schistura savona

    19. April 2022

    What the Corydoras are in South America, the Schistura loaches are in Asia. In hundreds of species they populate practically every stream and smaller river of the tropical and subtropical regions of the continent. In many cases, identification is difficult or impossible. Not so with Schistura savona from India. Its “half band” pattern with white […]

  • Acantopsis dialuzona

    9. March 2022

    In the last years we received horseface loaches (Acantopsis) mainly from Thailand, where the genus is represented by several species, which are difficult to distinguish. Now we have once again received specimens from Indonesia. It is A. dialuzona, the best known species of the genus by name. In older aquarium books this species can be […]

  • 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 […]

  • 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 […]

  • 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 […]

  • Hemimyzon nanensis

    8. February 2021

    With the import of Hemimyzon nanensis we were once again able to fill a white spot on the map of fishes that have become known in the aquarium with content. At least for us it is a first import. Hemimyzon belongs to the family of hillstream loaches (Balitoridae) and is closely related to the genus […]

  • Petruichthys brevis (= Yunnanilus brevis)

    27. January 2021

    Petruichthys brevis is a species of loach that originates from Burma. Here it occurs only in Inle Lake. The species attains a length of only 4-5 cm and thus belongs to the small species of fish. In contrast to most other species of loach, this one is a free swimming, schooling species. The swimming behaviour […]

  • Lepidocephalichthys kranos

    30. December 2020

    For the first time we can offer these cute dwarf spined loach from Vietnam. They become (without caudal fin) at most 3,5 cm long. Lepidocephalichthys kranos was not recognized as an independent species until 2010. The species differences in Lepidocephalichthys are very subtle (otherwise they would have been scientifically identified earlier), but it is quite […]

  • Vaillantella maassi

    20. November 2020

    This is certainly one of the most peculiar loaches ever. The genus Vaillantella – at present three species are distinguished – has a band-shaped dorsal fin running over the entire back, while all other loaches have relatively short, triangular dorsal fins. 

    Vaillantella are black-water-inhabitants and become 12-15 cm long, usually remain however clearly smaller; V. maassi is widespread in the peat-swamp-areas of Malaysia and Borneo, a habitat extremely endangered through destruction for oil palm plantations. Unfortunately, therefore all fish (and other living beings), that occur there, must be classified as highly endangered. The catch of ornamental fish can help to preserve at least parts of these biotopes as economic areas and is therefore an active environmental and species protection.

    Vaillantella maassi has so far only very rarely been kept in aquariums. One should care for it analogous to the well known Kuhli loaches (Pangio). The very large, forked tail fin enables Vaillantella an explosive propulsion; the aquarium must be covered therefore absolutely gaplessly, so that the animals do not land on dry land, if they are grabbed by the well-known wandering instinct, which many loaches show temporarily in the aquarium.

    For our customers: the animals have code 473053 on our stocklist. Please note that we exclusively supply the wholesale trade.

  • Sewellia “breviventralis”

    17. July 2020

    From Vietnam we have once again been able to import beautiful hillstream loaches of the genus Sewellia under the name Sewellia breviventralis. The species S. breviventralis exists and it is anatomically very similar to the imported animals, but there are differences in colouring compared to the live imported animals, whose exact origin is unknown, but […]

  • Yasuhikotakia (formerly: Botia) eos

    17. June 2020

    This beautiful and interesting loach, which can attain a maximum length of about 12 cm, originates from Thailand. This type of loach is said to be sometimes very aggressive. Y. eos is considered as one of the most aggressive species of all. However, in most cases this is a mistake of the keeper. Y. eos […]

  • Botia striata

    10. June 2020

    Currently we have very nice zebra loaches, Botia striata, in stock. The animals have an ideal size, 3-4 cm. The maximum length the species can reach is about 6-8 cm. In many species of loach the generic name has changed in the past years. The Clown loach, formerly known as Botia macracanthus, is now Chromobotia […]

  • Barbucca diabolica

    27. April 2020

    Currently we managed once more to import one of the cutest loaches from Borneo. Barbucca diabolica is despite its terrifying name a totally peaceful animal. Sadly almost nothing is known about the species. In nature, it lives in small forest streams in the Kapuas system on Borneo. Our animals have already almost the size of […]

  • Hemimyzon nanensis

    6. April 2020

    With the import of Hemimyzon nanensis we were once again able to fill a white spot on the map of fishes that have become known in the aquarium with content. At least for us it is a first import. Hemimyzon belongs to the family of hillstream loaches (Balitoridae) and is closely related to the genus […]

  • Pangio alternans

    3. April 2020

    Kuhlii loaches (Pangio) are very popular aquarium fish. They are cute, small and often colourful. In community aquariums the small water snakes act as a cleaning crew, which reliably prevents food residues from being left lying around. The animals are completely peaceful and love the company of conspecifics. Kuhlii loaches become restless before thunderstorms and […]

  • Inlecypris auropurpureus

    6. September 2019

    The Inle Lake in Burma has a high proportion of endemic fish species, i.e. fish that occur exclusively there. One of them is Inlecypris auropurpureus, a Danio with vertical stripes on a golden band. The number and shape of the stripes are slightly different for each individual. Inlecypris is closely related to the species placed […]

  • Paracanthocobitis rubidipinnis

    21. August 2019

    This beautiful loach comes from Burma, where it is found in the Irrawaddy system. They are exceptionally lively animals that are constantly in action with each other. For this reason, it is not acceptable to combine fish that love peace with Paracanthocobitis rubidipinnis. The animals – they become about 6-7 cm long – are however […]

  • Mesonoemacheilus triangularis

    9. August 2019

    The loaches of Asia are an enormously species-rich fish group. Similar to the cory catfish in South America, a great part of the species has not yet been scientifically described.  A well recognizable species is the Zodiak Loach, Mesonoemacheilus triangularis, from South India; here it occurs endemically in the Western Ghats. The genus Mesonoemacheilus differs […]

  • Gastromyzon viriosus

    2. April 2019

    We were able to import this charming zebra hillstream loach from Indonesia. The determination of the numerous species of Gastromyzon from Borneo (more than 30 different species are known from the island) is quite tricky, many species look quite similar to each other. So we cannot exclude the possibility that our fish will proof to […]

  • Syncrossus berdmorei

    29. March 2019

    The tiger loaches (Syncrossus) are a genus of comparatively large (about 15 cm), beautiful loaches. Formerly they have been added to the genus Botia. Currently five species are distinguished, among them Syncrossus berdmorei. Sadly this species is offered only occasionally, because it belongs to the most colorful species of the genus. The natural distribution of […]

  • Ambastaia nigrolineata: It doesn´t have to be always sidthimunki….

    13. February 2019

    These dwarfish relatives of the clown loach have done a kind of odyssey in respect of the generic name in the past. Both were originally described in the genus Botia. Later they were placed in Yasuhikotakia. Only in 2012 they changed to the genus Ambastaia, which has been generated especially for them. This genus contains […]

  • Yasuhikotakia splendida

    8. February 2019

    The genus Yasuhikotakia was separated from the genus Botia by Teodor Nalbant in 2002 and currently comprises 10 species. Some of them are important aquarium fish like Y. morleti (older synonym: Botia horae) and Y. modesta.  The newest species on the ornamental fish market is Y. splendida, which was described as Botia splendida in 1995. […]

  • Homaloptera parclitella

    28. December 2018

    Hillstream loaches belong to the family of loaches. Probably the most beautiful species can be found in the genus Homaloptera. There are several closely related and similar looking species. In the German one calls it often “saddle-stain-loaches”, English, the animals become “lizard loaches” called. Homaloptera parclitella is an extraordinarily beautiful hillstream loach from the black […]

  • Micronemacheilus cruciatus (= Yunnanilus c.)

    4. June 2018

    This charming free swimming dwarf loach originates from Vietnam. It attains a maximum length of about 3.5 cm. For quite a long time it was placed in the genus Yunnanilus, but currently mot scientists see them in the monotypical (this means the genus contains only one species) genus Micronemacheilus. These fish are totally peaceful and […]

  • Mesonoemacheilus guentheri

    1. June 2018

    There are ten known species in the genus Mesonoemacheilus. They are small, 4-6 cm long, very lively loaches. All of them occur along the Western Ghats, a mountain chain along the west coast of India, the so called Malabar coast. These mountains border the inland against the Arabian Sea. The Western Ghats are a so […]

  • Ambastaia sidthimunki

    14. May 2018

    From northern Thailand originates the dwarfish Checkerboard Loach formerly known as Botia sidthimunki, then as Yasuhikotakia s. As it is a rather small (6 cm) and very peaceful species, it represents an ideal member for an asiatic community tank. There it can be kept together e.g. with small representatives of the genera Danio, Rasbora and […]

  • Pangio anguillaris

    16. April 2018

    The Kuhli loaches (Pangio, formerly Acanthophthalmus) form an important part of all smaller community tanks with a southeast Asian character. Here the small „watersnakeletts“ are cleaning and feed all the small food particles that might have been overlooked by the other fish. Of course the loaches have to be fed also; this is no problem […]

  • Acantopsis rungthipae

    29. November 2017

    You don´t know that name? We didn´t either, until some days ago a taxonomical revision of the horseface loaches of the genus Acantopsis was published. All loaches of the genus used to be named Acantopsis dialuzona in the trade (sometimes the synonym A. choirorhynchos was also used). Currently seven different species are considered to be […]

  • Yasuhikotakia modesta

    25. September 2017

    We received from Thailand this wonderful sport of the Blue Loach (Yasuhikotakia modesta, formerly known as Botia modesta). The species is well known for its variability. Most often the fish are blue with bright red fins, but the body colour can vary from blue over green to blue-grey and the fins can be anything from […]

  • Misgurnus anguillicaudatus

    23. June 2017

    We received beautiful weather loaches via Hongkong. The genus is characterized by the existence of ten barbels around the mouth. The funny name „weather loach“ was given in medieval times, when these loaches were kept in captivity as weather prophets. These fish breath not only via gills but have an additional breathing technique. When the […]

  • Pseudogastromyzon cheni

    25. April 2017

    Now the season for the charming hillstream loaches imported via Hongkong has started. There do exist several species and we also have several species in stock currently. There is a lot of confusion regarding the identity of two species of Pseudogastromyzon, namely P. cheni and P. myersi. Both species look almost identical. And both species […]

  • Danio sp. Hikari Blue & Yellow

    20. April 2017

    Hikari-Danios belong to a scientifically still undescribed species of Danio from Burma. The closest relative is Danio kerri. However, Hikari danios are by far more colorful than D. kerri and really beautiful fish. Keeping and breeding Hikari Danios is absolutely comparable to the very well known zebra fish, Danio rerio. Hikari danios attain a maximum […]

  • New Tiger Loaches from Indonesia

    23. March 2016

    The
    Tiger Loaches (Syncrossus) have been placed in Botia formerly. The
    members of Syncrossus have a very sharp head. Currently 6 species are
    recognized, two of them from Indonesia, namely Syncrossus hymenophysa
    and S. reversus. Both can be easily told apart, for B. hymenophysa has
    dark tiger stripes on a light ground, B. reversus light tiger stripes on
    a dark ground.

    Now
    we obtained Syncrossus from Indonesia that cannot be safely applied to
    one of the two species mentioned, although they are definitively closer
    to S. hymenophysa than to S. reversus. But the fish remind one much more
    to the also undetermined species of Syncrossus that appeared some years
    ago in the market and said to come from Laos.

    While
    the stripes on the flanks of the new Syncrossus from Indonesia vary a
    lot in number, the coloration of the fins is very uniform in all
    specimens observed. Most probably the new Tiger Loach will reach a
    maximum length of 15-20 cm as reported in the other Tiger Loaches. All
    Syncrossus are known to be quite aggressive fish. They should be kept in
    large aquaria with a lot of hiding places and in groups. At least five
    specimens are needed, otherwise the fish cannot develop their quite
    complex social behaviour.

    For
    our customers: the fish have code 401001 (3-4 cm) and 401102 (4-6 cm)
    on our stocklist. Please note that we exclusively supply the wholesale
    trade.

  • Serpenticobitis cingulata

    21. March 2016

    We received this beautiful loch from Thailand. The genus Serpenticobitis contains only three species, all described in 1997/98. They differ from each other only in pattern. The type species, S. octozona, has broad, dark vertical bands with only very narrow light interspaces. In S. zonata the interspaces are much broader; in both species he dark […]

  • Pseudohomaloptera sp – A new dwarfish hillstream loach from Vietnam

    19. January 2016

    For the first time ever we obtained this hillstream loach from Vietnam. The determination is pretty tricky. All features visible in live fish (position of the dorsal fin, coloration, position of the anus) lead to the genus Pseudohomaloptera, which currently includes six described species: Pseudohomaloptera tatereganii (Popta 1905), P. sexmaculata (Fowler 1934), P. leonardi (Hora […]

  • Yasuhikotakia sp New Cambodian Tiger

    16. December 2015

    Formerly all the deep bodies loaches from Indochina were placed in the catch-all genus Botia. This generic name should be used now only for the Indian species, while the species from Laos, Thailand, Cambodia, and Vietnam are placed in Ambastia, Syncrossus, and Yasuhikotakia. We now were able to import for the first time ever a […]

  • It doesn´t have to be always sidthimunki….

    26. August 2015

    These
    dwarfish relatives of the clown loach have done a kind of odyssey in
    respect of the generic name in the past. Both were originally described
    in the genus Botia. Later they were placed in Yasuhikotakia. Only in
    2012 they changed to the genus Ambastaia, which has been generated
    especially for them. This genus contains only two species, namely
    Ambastaia nigrolineata and A. sidthimunki. The genus is defined by the
    unique coloration of these species.

    Ambastaia
    nigrolineata occurs in Laos, Thailand, and China. However, like A.
    sidthimunki almost exclusively bred specimens are offered nowadays,
    because otherwise only a very seasonal availability would be given. A.
    nigrolineata stays almost as small as A. sidthimunki and becomes around
    7-8 cm long (including tail fin).


    Juveniles
    have only two black stripes on an ebony white body, later the males
    develope a pattern that is quite similar to that of A. sidthimunki.

    For our customers: the fish have code 404702 on our stocklist. Please note that we exclusively supply the wholesale trade.

  • Sinibotia robusta

    26. June 2015

    Every year in June is import season for Botia-like loaches from China. The genus Sinibotia currently contains six species. The genus Sinibotia differs from Botia by the presence of three pairs of barbel (two maxillary, one mandibulary), while in Botia a fourth pair of barbels is present on the lower lip. Sinibotia robusta is also […]

  • Sinibotia robusta

    Sinibotia robusta

    26. June 2015

    We received beautiful coloured Kansu loaches (Sinibotia robusta) from China. This comparatively peaceful species is best kept at room temperature (18-24°C) without an additional heater. Only very few specimens available! For our customers: the fish have code 405053 on our stocklist. Please note that we exclusively supply the wholesale trade. Text & photo: Frank Schäfer

  • Homaloptera cf. leonardi Vietnam

    17. June 2015

    We were able to import once more hillstream loaches from Vietnam. Instead of the expected Annamia normai (see http://www.aquariumglaser.de/en/fish-archive/loaches-en/Annamia_normani_en/) we received another species. The determination is a very tricky thing. The most coincidences are to the species Homaloptera leonardi. Especially the scale-less zone between pectoral and ventral fins is said to be very typical for […]

  • Homaloptera parclitella

    25. March 2015

    Hillstream loaches are – in general – rather dull coloured fishes. However, there are exceptions and among the most beautiful species are those belonging to the genus Homaloptera. Several, closely related and quite similar species exist. In German they are called “saddle-back loaches”, a commonly used English name is “lizard loaches”. For the first time […]

  • Protomyzon pachychilus – season for Panda loaches!

    23. March 2015

    The extremely charming juveniles of the Panda loach are available only a few weeks per year. Obviously this year was a good one for the fish and they have bred very successful, because a comparatively large number of specimens is offered for comparatively low prices. Among the good number of specimens we were able to […]

  • Somileptes gongota

    9. February 2015

    Once more we received the fascinating cat-eyed loach, Somileptes gongota, from India. These fish are sand bottom dwellers that originate from higher regions. Temperature between 16 and 24°C, the water must be very clean and poor in bacteria, pH and hardness are of lesser meaning (in the wild, the water has a pH around 7 […]

  • Schistura spilota

    Schistura spilota

    16. January 2015

    The loaches of the genus Schistura are spread all over South and Southeast Asia. They have much in common with the catfishes of the genus Corydoras from South America: they are present everywhere and there does exist a large number of species. Schistura spilota from Thailand is one of the largest species at all and […]

  • A new ornate hillstream loach

    24. September 2014

    The
    genus Sewellia has made the hillstream loach popular in the hobby. The
    splendid Sewellia lineolata is named also orante hillstream loach.
    However, there are more beautiful species in the genus which are
    imported now and then. Sadly it is often not possible to determine them
    exactly. We were able to import one of the latter species now.

    In any case this ornate hillstream loach is a real enrichment for the aquarium hobby!

    For our customers: the fish have code 455044 on our stocklist. Please note that we exclusively supply the wholesale trade.

    Large Emperor Loaches arrived!

    3. July 2014

    For
    the first time we obtained Emperor Loaches (Leptobotia elongata) of a
    size of 14-18 cm. However, this is not the maximum length reported for
    that wonderful species! It is said to reach 50 cm and 3 kg in weight!
    Sadly the gorgeous species is highly endangered in the wild. It is known
    only from the upper and middle Yangtse River. Of course the species is
    not endangered due to the collecting for the ornamental fish trade, but
    due destruction of the natural habitat. Luckily it is possible to breed
    this loach in captivity. The Emperor Loach should be winterhardy even in
    garden ponds in Central Europe.

    For our customers: the fish have code 400404 on our stocklist. Please note that we exclusively supply the wholesale trade.

  • Traccatichthys taeniatus

    27. June 2014

    For the first time ever we could import this pretty, red-finned loach from Vietnam, which has the popular name “Peppermint Loach” due to the bright green shine on the flanks. The species attains a length of about 12 cm and is very peaceful. One should keep these fish always in groups, for they are very […]

  • Yunnanilus brevis

    17. June 2014

    Yunnanilus brevis is a species of loach that originates from Burma. Here it occurs only in Inle Lake. The species attains a length of only 4-5 cm and thus belongs to the small species of fish. In contrast to most other species of loach, this one is a free swimming, schooling species. The swimming behaviour […]

  • Lepidocephalichthys guntea – die ideale Aquarienschmerle

    Lepidocephalichthys guntea – the ideal aquarium loach

    12. March 2014

    There is hardly a second species of loach that is as good suited for the home aquarium as Lepidocephalichthys guntea is. The species becomes usually 6-8 cm long, only in very rare occasions larger specimens up to 15 cm have been reported in literature. The animal has a huge distribution area over the north of […]

  • Annamia normani

    31. July 2013

    This top-rarity among the hillstream loaches reached us from Vietnam, where the genus Annamia is represented by this single species. A second, formally described species (A. thuathiensis), also from Vietnam, needs to be researched. A. normani has also been reported from Laos and Cambodia. Annamia normani attains a maximum length of about 10 cm and […]

  • Somileptes gongota

    28. December 2011

    For the first time we received the fascinating cat-eyed loach, Somileptes gongota, from India. These fish are sand bottom dwellers that originate from higher regions. Temperature between 16 and 24°C, the water must be very clean and poor in bacteria, pH and hardness are of lesser meaning (in the wild, the water has a pH […]

  • Yasuhikotakia nigrolineata

    Yasuhikotakia nigrolineata

    16. August 2010

    This pretty loach is distributed in Laos, Thailand and parts of China. Obviously it is a close relative of the dwarf chain loach, Y. sidthimunki, and the behaviour of Y. nigrolineata is absolutely the same. However, there are two distinguishing features – besides the coloration: first, Y. nigrolineata become a bit larger, about 8 cm […]

  • Yunnanilus sp.

    Yunnanilus sp.

    2. February 2010

    The genus Yunnanilus comprises a comparably high number of species: 30 species are currently recognized as valid, but there are for sure much more species. Most known species have a very small distribution area. If you realize that only a very small part of the waters in the area of the genus have ever been […]

  • Sewellia speciosa

    26. January 2010

    Currently we were able to import this nice hillstream loach from Laos for the first time. The species is restricted to the Kong river influence in Laos and Vietnam. Maximum length is around 6 cm. The species has a very interesting sexual dimorphism. Males – which are in general more tiny than females – develope […]

  • Hillstream loach week at Aquarium Glaser! Part 4: Chinese Rarities

    27. March 2009

    Vanmanenia pingchowensis
    Only three specimens of this attractive species were imported recently. The fish are about 8 cm long and seem to be almost fully grown. The species is found in mountain strams, where they live on the bottom between pebbles.

    Erromyzon sinensis
    This is a small species, reaching hardly 5 cm. It is interesting that they differ much in coloration. Some specimens are almost uniform brown while others have a pattern of fine stripes. The species is restricted to the West River.

    Sinogastromyzon wui
    This is the only hillstream loach of today´s update that we have more or less regulary in stock. They are very pretty and reach around 6 cm in total length. The species is found on the island of Hainan and in the Zhujiang River on the Chinese mainland. Golden (xanthotistic) specimens occur regularly. Normally the basic colour of the fish is a warm brown.

    Hillstream loach week at Aquarium Glaser! Part 3: Crossostoma lacustre, Homaloptera tweedei, Gastromyzon punctulatus

    25. March 2009

    Crossostoma lacustre

    Crossostoma lacustre is a species that we were able to import for the very first time now. It is endemic on Taiwan. That means it occurs nowhere else in the World. Despite its scientific name (lacustre means: „Living in a lake“) it is found in nature only in heavily torrent waters of small brooks. The maximum size reported for that species is 12 cm.
    Homaloptera tweedei

    Homaloptera tweedei is a chraming dwarf species that reaches only 4-5 cm in length. Although it is not that much colorful it is a real eyecatcher due to its funny behaviour. In nature – we get this species from Thailand – it lives in medium sized streams where it swims over on large stone plates and stuff like that.

    Gastromyzon punctulatus (G. ctenocephalus?)

    The island of Bormeo is home to a very large number of hillstream loaches. Sadly it is virtually imposible to give a correct name on them, although a great revision of these fishes was published quite recently (2006). But there are many species which are known already but which are not yet described formally and thus it is impossible to identify them. So in the trade we use the catch-all name Gastromyzon punctulatus for this group of species, as it was also usually in the scientific literature until 2006.

    Leaving the difficulties in naming the species aside these spotted hillstream loaches are wonderful aquarium inhabitants. As they come from tropical areas they can be kept in heated tanks. The species we actually have in stock has very nice blue fin membranes, but sadly they show them only for a very short time. The fish become 6-7 cm long. Their body coloration varies between light brown and deep black. Scattered over this ground coloration are yellow spots of different size. Currently our species is often identified as G. ctenocephalus.

    Gastromyzon punctulatus (G. ctenocephalus?)

    For our customers: Crossostoma lacustre has the code 412692, Homaloptera tweedei 421632 and Gastromyzon punctulatus 416562. Please note that we exclusively supply the wholesale market.

    Hillstream loach week at Aquarium Glaser! Part 2: Beaufortia leveretti

    24. March 2009

    This is by far the most often offered hillstream loach. It originates from China and Vietnam, but is currently imported from China only. The whole habitus is very similar to the Sewellia species we presented yesterday. The coloration is formed by pretty black spots on golden underground.

    The most important fact one has to know about B. leveretti is that this is not a tropical fish at all, but comes from moderate climate zones. Thus it is impossible to keep it in a long time sight at water temperatures above 24°C. The ideal range is 12°C in winter and 21°C in summer. Avoid abrupt jumps in temperature!

    B. leveretti is therefore an ideal inhabitant of unheatet aquaria and helps you to save energy costs. A perfect tankmate for B. leveretti is the White cloud mountain minnow, Tanichthys albonubes. A school of that fish containing about 15-20 specimens in the water column and 10-12 Beaufortia form a very nice picture.

    Hillstream loach week at Aquarium Glaser! Part 1: Introduction & Sewellia

    23. March 2009

    Currently we can offer a great number of varieties off hillstream loaches. That´s the reason for this week´s special. We want to show you how interesting and diverse these fishes are.

    Sewellia lineolata

    Systematically speaking, the hillstream loaches belong to the family Baltoridae. This means that they are close relatives of the river loaches (Nemacheilus, Schistura etc) which are also members of the Balitoridae. Hillstream loaches are adapted to live in fast flowing water. Their pectoral and ventral fins are formed like the spoiler of a car and have the very same function: the water that flows over the fish presses them down. So the fish can withstand the current without much loss of energy.

    In some species this fin apparatus is so effective that it enables the fish to climb over water falls!

    As they are relatives of the river loaches they feed on a great variety of small animals, but they do not eat algae! In the aquarium they will accept frozen food, live food and many will also take dried food. Among each other they are usually peaceful. Short huntings are the worst they have to face from congeneers. Other species become usually totally ignored.

    The tank setup for hillstream loaches should be orientated on a brook. It should content stones and roots. Plants are of minor interest for the fishes. One should know that all hillstream loaches are very sensitive against nitrite.

    Breeding hillstream loaches was successful in recent times. Since the first importation of the spectacular Sewellia lineolata aquaristis developed a great ambition to breed them. Females are larger and thicker. They spawn almost daily over a long period. Breeders offer clusters of pebbles with 2-4cm granualtion. The eggs disappear in these clusters and cannot be eaten by the always hungry parents. The gaps between the pebbles are also home for the fry until they are big enough to leave them without being in danger to end as food for the parents.

    Sewellia sp. “Spotted”

    Our journey through the world of hillstream loaches starts with Sewellia. We have in stock three species from Vietnam: Sewellia lineolata that can grow up to 6.5–7cm, an undescribed species called S. sp. „Spotted“ and for the first time ever S. breviventralis. The latter has been described in the year 2000. The scientists knew at the time only juvenile specimens. We can offer also adult specimens of about 6cm length. Many specimens show broad barres over the back, but the coloration varies a lot individually and there are also almost plain animals.

    Sewellia breviventralis

    Although S. breviventralis is known as an extremely rheophilous species they thrive very well in captivity. All three species of Sewellia should be kept at temperatures between 18 and 24°C. Higher temperatures over a long period lead to starving fishes. Their metabolism then needs more energy than the fish can feed. The remaining water conditions are of minor interest. Moderatly hard water with a neutral pH is perfect.

    Sewellia breviventralis

    For our customers: Sewellia lineolata has codenummer 455054, S. breviventralis 455043 and S. sp. „Spotted“ 455075 on our stocklist. Please note that we exclusively supply the wholesale market.

  • Protomyzon pachychilus

    2. March 2009

    For the first time we were able to import these charming hillstream loaches. Due to their origin (China) and their black&white coloration we call them dwarf panda hillstream loaches. Although the species has been scientifically described back in 1980 in a Chinese journal almost nothing has been published concerning the beautiful animal since then. Our […]

  • Schistura cf. jarutanini

    Schistura cf. jarutanini

    19. February 2009

    The brook loaches of the genus Schistura are far spread over South and Southeast Asia. There are hundreds of species, most of them still scientifically undescribed. Almost each flowing water has it´s own species. So it is no surprise that some of the species also became cave-dwellers. We could import a small number of individuals […]

  • Acantopsis sp.

    7. November 2008

    (Nov.6th 2008)Due to its unusual head shape the horseface loach A. coirorhynchos is one of the most popular aquarium fish. In nature they often are residents of clear rivers, where you can find them especially on sandy grounds. Inside the aquarium you also have to provide sandy ground, which allows them to completely bury themselves. […]

  • Sinogastromyzon wui

    18. February 2008

    (18. Feb.2008) Last week we received this loach which was described by FANG 1930. Their habitat is from the Nanpan-jiang and Xi-jiang basins in Guangdong to Guanxi provinces in China. The maximum size is about 8-10cm. They should be kept in cold water, not over 22-23°C, and they have very high oxygen requirements. To offer […]

  • Homaloptera tweediei

    14. February 2008

    (14.Feb.2008) The adult size of the gecko-loach, Homaloptera tweediei, is only approx. 4cm. This species is very interesting for the hobbyists, because they can be kept for a longer period in a water temperature of more than 24°C. The main reason is the origin in central Thailand. After acclimatisation they are very thankful and easy […]

  • Sewellia sp. Spotted

    19. December 2007

    (19.Dec.2007) This, very attractive, probably scientifically not described hillstream sucker reached us from Vietnam. They remember on Sewellia lineolata but their point pattern is finer and also is the for S. lineolata characteristic “stripe” missing. Like all hillstream suckers they come from fast flowing water, there they inhabit rapid flowing streams where they graze on […]

  • Schistura pridii

    Schistura pridii

    19. October 2007

    (19.Oct.2007) Last week we received another new item: Schistura pridii. This beautiful small loach (grows up to 4.5cm) comes from Thailand. Exactly they were found in the upper Chao Praya Bassin in the Chiangmai province in the north of Thailand. They come from cool (18-24°C) & fast floating rivers, containing hard and alkaline water, which […]

  • Yunnanilus brevis

    17. July 2007

    They behave like barbs, scientifically however they belong to the loaches. Completely contrary to the bottom-oriented way of life of their relatives they populate the free water range as swarm fishes. Their homeland is Burma, where they live in slowly flowing waters and the boundary region of lakes. With a length of approximately 6 cm […]

  • Schistura nicholsi

    6. July 2007

    To an unusually large about 200 species comprehending genus belongs Schistura nicholsi the Redtail Zebra Sand Loach. It originates from the Mekong basin in Thailand and Laos, where it inhabits fast flowing waters on a stony ground. This is to be considered during its aquarium maintenance. In order to ensure a high oxygen content and […]

  • Yasuhikotakia lecontei

    6. July 2007

    From the watershed of the Mekong originates this circa 15 cm long getting loach. The name red finned loach is something misleading, since not all animals show this colouring in all stages of age. During their development they change colours and pattern. Young animals usually exhibit a pattern of stripes which disappears during ageing. In […]

  • Yasuhikotakia sidthimunki

    6. July 2007

    From northern Thailand originates the Dwarf Loach formerly known as Botia sidthimunki. Since it is a rather small (6 cm) and very peaceful species, it represents an ideal member for an asiatic community tank. There it can be kept together e.g. with small representatives of the genera Danio, Rasbora and Microrasbora . One should always […]

  • Botia sp. „New Emperor“

    6. July 2007

    The ever first import of Botia sp. “New Emperor”, probably comes from the borderland of Burma/Thailand. It should appear in a decadal yearly rhythm in a large amount and can only be caught then. An area informed ichthyologist stated that transportation through bordering hilly regions can only be helped by small mopeds, where a slight […]

  • Chromobotia macracanthus

    6. July 2007

    In our picture you see an interesting mutant of the clown loach, which reached us these days. Although Chromobotia macracanthus formerly known as Botia macracantha is a long time tank inhabitant, it is still not without mysteries. This applies particularly to the breed, so far we have only coincidence success. Also in the maintenance they […]

  • Sewellia lineolata

    6. July 2007

    Sewellia lineolata belongs surely to the most attractive hillstream loaches. Their origin is the of the Mekong basin in China, Viet Nam and Cambodia. There they inhabit fast flowing water sections with rapids and riffles. In the aquarium they like it not to hot a heater is not necessary for their well-being. As day-active insecteaters […]

  • Schistura beavani (falsch bestimmt: S. scaturigina)

    Schistura beavani (wrong determined: S. scaturigina)

    6. July 2007

    This loach belonging to the family of River loaches (Baltoridae) originates from Darjeeling and Assam in the eastern Himalayan mountains, Northern India, Nepal and Bhutan, where it lives in fast streaming rivers. This is a peaceful species, which is suitable for a well-kept aquarium. This loach should be nurtured in a well filtered and aerated […]
