09. Characoids: tetra relationship (380)

  • Cynopotamus atratoensis

    Cynopotamus atratoensis

    6. July 2007

    Only three of these predatory characins found their way to Aquarium Glaser. This group of characins form the subfamily Cynopotaminae within the family of real American characins (Characidae). The representatives of this subfamily are relatively large fish, which can reach a total length between 15 and 30 cm in adulthood. Cynopotamus have large mouth openings […]

  • Brittanichthys myersi

    6. July 2007

    This interesting, rarely traded characin species origins from the Rio Negro area. B. myersi is a genuine black water fish, which should be kept best at pH values of 4,5 – 6 and a very low water hardness. A filtering over peat can be very helpful, apart from the improvement of the chemical parameters the […]

  • Ammocryptocharax sp. „spotted“

    Ammocryptocharax sp. „spotted“

    6. July 2007

    This scientifically undescribed ground tetra originates from Peru. This is a peaceful species also when housed with delicate fish. This is a medium size tetra fish, which probably does not grow larger then 5 cm. If more then one male of this ground tetra inhabits the tank then they can become somewhat territorial and therefore […]

  • Hyphessobrycon haraldschultzi (= spec. „Araguaia“)

    Hyphessobrycon haraldschultzi (= spec. „Araguaia“)

    6. July 2007

    Red fish always attract interest amongst hobbyists, especially the intensively red coloured ones. Five years ago when we received the first animals of this tetra by the name of “Hyphessobrycon serpae – the real one” (wildcaught from Rio Araguaia), we were immediately enthusiastic, too. At first sight (still inside the transport bag) these tetras looked […]

  • Sartor respectus

    Sartor respectus

    6. July 2007

    This representative of the head standing characins originates from the upper Rio Xingu in Brazil. These peaceful fish can often be found in small groups. Vegetarian food should not be omitted in its menu if we want this fish to thrive and grow well. Research on the stomach contents in nature, showed that these fish […]

  • Hyphessobrycon sweglesi

    Red Phantom tetra, Hyphessobrycon sweglesi

    6. July 2007

    Until a few years ago Red Phantom tetra, Hyphessobrycon sweglesi was easy to identify, even though under the name of Megalamphodus sweglesi. Lately “Red Phantom Tetras” appear more often, which are very similar to it, but also show other characteristics. It stays (temporarily) unclear, if they are own species, subspecies or “local forms”. Interested hobbyists, […]

  • Serrasalmus cf. marginatus

    6. July 2007

    From south Brazil we could import a further Serrasalmus species. Probably it is Serrasalmus marginatus, a final species diagnosis is not yet present. Their max. size lies clearly below 30cm. There are some reports existing about a successful maintenace in groups, but socialisation is always a little bit risky for such hazardous fishes and their […]

  • Hasemania sp. „Red“

    Hasemania sp. „Red“

    6. July 2007

    This small characin is a very attractive fish and a fast swimmer as well. It could be determined as a representative of the Hasemania genus, because it misses the characteristic adipose fin, which is one of the features that determine characins. Up to now we used to have only one species belonging to this genus, […]

  • Hyphessobrycon takasei

    Hyphessobrycon takasei

    6. July 2007

    ++ Wild collected Hyphessobrycon takasei currently (December 2010) arrived ++ After seeing and purchasing this beautiful tetra from the under Amazonas basin (Amapá area) at AQUARIUM GLASER for the first time, we were not sure in the beginning, if it is definitely Hy. takasei, because its shoulder spot seemed a little to small to us. […]

  • Hyphessobrycon bifasciatus

    6. July 2007

    The Yellow Tetra originates like its close related Von Rio Tetra from coastal rivers in southeast Brazil. With its pretty yellow basic colour it forms a beautiful contrast to it and other reddish characin species. As a schooling fish the Yellow Tetra should be kept only in larger swarms. Particularly in not too brightly lit […]
