09. Characoids: tetra relationship (414)

  • Moenkhausia nigromarginata

    23. July 2021

    Again we can announce a first import: Moenkhausia nigromarginata. For the first time ever we received some of these tetras described in 1994. The species reaches a length of about 5 cm. Striking are the blue eye, the blue back in incident light and the – sometimes more and sometimes less visible – zigzag bands […]

  • Hyphessobrycon moniliger

    19. July 2021

    Under the name “Hasemania hansseni” a new tetra has recently appeared on the market, which with its intense orange coloration is indeed somewhat reminiscent of the well-known copper tetra, Hasemania nana. However, one of the characteristics of the genus Hasemania is that it lacks the adipose fin that is so typical for tetras. This is […]

  • Moenkhausia rubra

    16. July 2021

    New legislation in Brazil now allows the import of species whose export was previously not allowed. One of these species is Moenkhausia rubra, which was only scientifically described in 2014. The species is so far known only from the Rio Juína and the Rio Juruena, both belonging to the upper Rio Tapajós drainage, Mato Grosso […]

  • Hyphessobrycon sp. “Muzel Red Cherry“

    7. July 2021

    From Brazil we received this really nice novelty, which looks a bit like an enlarged edition of the Ember tetra, Hyphessobrycon amandae. However has the “Muzel Red Cherry” two (although indistinct) shoulder spots, which never occurs in H. amandae.  In addition, the dorsal fin in “Muzel Red Cherry” is red with a light margin, while […]

  • Hyphessobrycon eques “Longfin”

    28. June 2021

    The Serpa Tetra, also called the Callistus Tetra (Hyphessobrycon eques, formerly known as H. callistus or H. serpae), is the little man’s piranha. Just like piranhas, serpa tetras have an irresistible urge to bite the fins of other fish. And they constantly want to test out who is the stronger. This makes many exciting observations […]

  • Pygocentrus nattereri

    25. June 2021

    The red-breasted shoaling piranha (Pygocentrus nattereri) is present throughout the Amazon River basin. It is the most common piranha species kept in aquariums. The breeding of these animals succeeds according to plan. Pairs are formed from a shoal, which spawn in bottom pits; the parents guard the spawning site, there is no brood care beyond […]

  • Leporinus ortomaculatus

    21. June 2021

    For the first time we can offer this pretty Leporinus, which was scientifically described only in 2000. Be careful not to confuse it with L. octomaculatus, because this is a completely different species; here the confusion of one letter has consequences!  So far Leporinus ortomaculatus is known from the Rio Surumu, Roraima, Brazil and from […]

  • Which Semaprochilodus comes from Indonesia?

    16. June 2021

    Quite clearly – none at all! Because this genus is exclusively from South America. But in Indonesia these beautiful large tetras are bred and occasionally we import juveniles from there. Then one wonders which species it is. We get them as S. insignis and so we sell them on, but is the determination correct? This […]

  • Psalidodon anisitsi (= Hyphessobrycon a., Hemigrammus caudovittatus)

    7. June 2021

    One of the oldest aquarium fishes is the Buenos Aires tetra, of which the correct scientific name was only recently determined: Psalidodon anisitsi. To most aquarists, however, the species is probably still known as Hemigrammus caudovittatus (or Hyphessobrycon anisitsi), and it is under this name that it is found in most aquarium books. Since its […]

  • Nannostomus beckfordi

    4. June 2021

    Nannostomus, also known as pencil fish, propel through the aquarium like small, colorful zeppelins. The unusual, somewhat stiff-looking swimming style makes them unique in the colorful world of tetras. There are quite a few species of Nannostomus-species, but the Red Pencilfish (Nannostomus beckfordi), which grows up to 6.5 cm long (but appears smaller due to […]
