  • Oryzias javanicus

    13. March 2020

    The rice fish (Oryzias) have been in the focus of aquarists for several years. First the fantastically colored O. woworae were discovered on Sulawesi, then the Japanese Medakas (O. latipes) experienced a renaissance, because many interesting new breeding forms developed. Most species of the genus, which comprises more than 30 species, occur quite locally. Two […]

  • Brittanichthys axelrodi

    From the catchment area of the Rio Negro these interesting, rarely traded characins reached us. Brittanichthys axelrodi is a true black water fish, which should be kept at pH 4.5 – 6 and low hardness. Filtering via peat can be very helpful here. In addition to improving the chemical parameters, the bactericidal effect of peat […]

  • Pseudorinelepis sp. L95

    9. March 2020

    The loricariids of the genus Pseudorinelepis are the most heavily armored loricariids at all. They are widely distributed in the basins of the large South American rivers Amazon and Orinoco. The imported animals often look a little bit different, but scientifically only one species, P. genibarbis, is recognized at present. The coloration varies greatly individually, […]

  • Puntioplites falcifer

    6. March 2020

    These large barbs differ from all other barb relatives by an easily recognisable external feature, namely a strong ossified anal fin spine, which can be smooth or serrated. Within the Cyprinidae in a broader sense only carp and crucian carp show this anatomical feature, but these two genera are not barbs. So while the genus […]

  • Paedocypris: the smallest fish in the world

    With a length of 7 mm the females of the smallest fish species in the world, Paedocypris progenetica, become sexually mature. And also the two other scientifically described species, P. carbunculus and P. micromegethes, grow only a few mm longer. All species occur in very acidic black waters in Indonesia and Malaysia. The genus name […]

  • Betta raja

    4. March 2020

    With 73 species generally regarded as valid, the genus Betta has become rather confusing and without knowledge of the origin, even specialists find it difficult to identify the species. We have just received very beautiful mouth-breeding Bettas from Sumatra, including Betta raja. Betta raja belongs to the closer relatives of Betta pugnax. The most reliable […]

  • Garra lissorhynchus

    Algae eaters do not have to be pretty, they should eat algae. This basic motto also applies to Garra lissorhynchus, for which the name “chocolate algae eater” was coined to promote sales, but which is mainly dressed by friendly grey tones. The 1-3 cm long juveniles of this species, which comes from India, or more […]

    After our excursion to the Rio Guaviare we went by boat in direction to Rio Inirida, up the river of the same name up to the Caño Bocón. The Caño Bocón is a small tributary of the Rio Inirida that carries black water. Leonell catches his fish here, which we later keep in our aquariums […]
