  • Red Gars

    19. April 2021

    From Indonesia we have received captive bred specimens of a gar species, which stands out due to its reddish brown (normally blackish, gray or silver) basic coloration with partly brick-red coloration parts. Unfortunately, it is not possible for us to name the species correctly, because the reliable identification of gar is only possible on the […]

  • Boraras merah

    16. April 2021

    Currently we have very nice Boraras merah in stock. The species is a very close relative to B. brigittae and at least in some populations the females of B. merah look like B. brigittae and only the males have a typical B. merah pattern (see also http://www.aquariumglaser.de/en/boraras-brigittae–boraras-merah_de_1107.html). Cross-breeding experiments also show that both varieties are […]

  • Monodactylus argenteus

    16. April 2021

    Moonies are magnificent brackish water fish. In pure fresh water they should be kept only temporarily, if possible, because they are very sensitive there. If it has to be freshwater, then the pH value must not drop below 7 and the nitrate value must not rise above 50 mg/l, nitrite is harmful even in very […]

  • Glyptothorax cf. housei

    14. April 2021

    The belly sucker catfishes (Glyptothorax) are almost unknown in aquaristics. It is a very species-rich group (over 100 accepted plus probably still numerous undescribed species) of mostly small, current-loving catfishes. The extremely sparse care experiences with these catfishes show that they are (as with many stream fishes) sensitive animals, which tolerate neither stronger organic pollution […]

  • Atyopsis moluccensis

    12. April 2021

    Among the numerous shrimp species that have gained a firm foothold in the hobby are two larger species of fan shrimp, namely Atyopsis moluccensis, the Moluccan mountain rock shrimp from Southeast Asia, and Atya gabonenis, the Gabon giant fan shrimp from West Africa. They grow relatively large (A. moluccensis approx. 9 cm, A. gabonensis approx. […]

  • Rineloricaria heteroptera

    9. April 2021

    From Brazil we received beautiful whiptail catfishes, which we thought at first sight to be Rineloricaria lanceolata, a species with a very wide distribution. The high proportion of reddish animals was striking.  The majority of the fish are small, 3-4 cm long and marked like R. lanceolata, but there are a few adult specimens among […]

  • Corydoras cf. armatus “Spotted Putumayo“

    9. April 2021

    From Colombia we received a nice Corydoras species, which threw us into some confusion during identification. They were sent as C. armatus, a species described from the Rio Huallaga, a right-bank tributary of the Rio Maranon (the larger of the two headwaters of the Amazon) in Peru.  C. armatus is a conspicuously high-backed species with […]

  • Epalzeorhynchos kalopterum

    7. April 2021

    The Flying Fox, Epalzeorhynchos kalopterum (Epalzeorhynchos is neuter, so if the species name is an adjective – as in this case – it must end in the Latin neuter suffix -um), originates from Indonesia, Malaysia and Thailand, where it is a resident of flowing waters that carry deep dark brown black water. They are probably […]

  • Poecilia velifera Silver

    6. April 2021

    Silver mollies are among the most popular livebearers. Most of the silver mollies in the trade are a breeding form of Poecilia latipinna. Since the species Poecilia latipinna, P. sphenops, P. mexicana and P. velifera can be crossed and color characteristics and certain fin shapes (e.g. lyratail) are transferred to the hybrid young, the desired […]

  • Xiphophorus hellerii “Yucatan 2”

    1. April 2021

    From a German breeder we received this extraordinarily attractive wild form of the swordtail. Unfortunately we could not find out where exactly and by whom these animals were collected. It could only be determined that they were originally brought from Yucatan (Mexico). As a distinction to the completely different looking X. hellerii “Yucatan” (see https://www.aquariumglaser.de/en/fish-archives/xiphophorus_hellerii_yucatan_en/) […]
