  • Dichotomyctere ocellatus (formerly: Tetraodon biocellatus)

    29. March 2019

    The green pufferfish (genus Dichotomyctere) are the best known aquarium pufferfish. They are brackish water animals, which, in case they should be cared for in fresh water, paying special attention to their pH value. A pH below 8 does not get them in the long run and the water should be as hard as possible. […]

  • Peckoltia sp. L135

    27. March 2019

    Currently is season for one of the most beautiful members of the genus Peckoltia, namely L135. The species originates from the Rio Negro and can be easily recognized by the “wormline-pattern” on the head. Only two other species of Peckoltia show a similar pattern: P. braueri from the Takutu river and P. sp. L121 from […]

  • Betta pi

    25. March 2019

    Why is an endangered, mouth-breeding fighting fish called like the mathematical circle number? Not so long ago, in 1986, the first of the these big fighting fishes was discovered in Malaysia by travelling labyrinth fish enthusiasts and described as Betta waseri in honour of Alfred Waser, a primordial rock of the labyrinth fish scene. These […]

  • Andinoacara rivulatus

    22. March 2019

    Once colourful large cichlids were so popular that imports from Ecuador were organised mainly because of them. On the pacific side of the country live the “Green Terror”, so the then still Aequidens rivulatus named gold seam cichlids were called, and the “Red Terror”, then Cichlasoma festae, today Mesoheros festae. Both species become easily over […]

  • Melanotaenia boesemani Red

    22. March 2019

    The blue-red Boesemans rainbow fish has not disappeared from the aquariums since its aquaristic discovery in 1981. For a time, it was so sought after that it was caught on a massive scale for export; these animals went almost exclusively to Japan, where were paid insane sums for them. There were even fears of overfishing […]

  • Apistogramma cf. taeniata

    20. March 2019

    Nobody knows exactly what Apistogramma taeniata is, because the species was described in 1862 after a specimen, which is today in a very bad condition and the verbal description is more than scarce. At the time of the description, the genus Apistogramma did not yet exist, no one had any idea of its variety of […]

  • Cherax alyciae “Blue Kong”

    18. March 2019

    This crayfish was regarded as a particularly pretty variant of the zebra-lobster (Cherax peknyi) until recently and was called “Blue Kong” in the trade melodiously. Chris Lukhaup, Rury Eprilurahman and Thomas von Rintelen described it scientifically as Cherax alyciae in June 2018. We have just received these very attractive animals as wild catches from Indonesia. […]

  • Poecilia (Limia) tridens

    15. March 2019

    There is no agreement on the systematic position of the livebearers living on the Caribbean islands. According to anatomical characteristics, the genus Limia is today mostly regarded as synonymous with Poecilia, but they have so many independent characteristics that Limia is almost always mentioned as a subgenus.  Aquaristically this is not so important whether Limia […]

  • A new little tetra from Peru

    15. March 2019

    We admit it: when we unpacked the animals, we were just disappointed. Colourless tetras, obviously young, with a black longitudinal line. Quite great. Because of the round head form they reminded of the genus Bryconamericus, a very species-rich and difficult to overview genus, and because we had to book them somehow into the system, from […]

  • Hypostomus rhantos L242

    13. March 2019

    With almost 150 accepted species, the genus Hypostomus (in the broadest sense) is the most species-rich group of loricariid catfish. Unfortunately, there is no current revision of all species and so the determination of Hypostomus is usually a laborious affair, in the end often only a questionable result. Hypostomus rhantos is pleasingly easy to recognize. […]
