  • Xiphophorus xiphidium

    13. November 2020

    The sword platy, Xiphophorus xiphidium, belongs to the top rarities among the live-bearers. The species is found on the headwaters of the Soto La Marina River and its tributaries, Tamaulipas State, on the Atlantic side of Mexico. The very pretty species remains with approx. 3 cm (male) resp. 4 cm (female) clearly smaller than the […]

  • Parancistrus nudiventris, L31, LDA4, Peppermint Pleco

    13. November 2020

    This pleco from the Rio Xingu is an old friend, however, it received a scientific name only in 2005. It received the L-number 31 already in 1989.  The genus Parancistrus is closely related to the genus Spectracanthicus; the formerly often used genus Oligancistrus is invalid and declared synonymous with Spectracanthicus. The only difference between Parancistrus […]

  • Serrasalmus elongatus

    11. November 2020

    This very elongated Piranha can be confused hardly with other species because of its characteristic body shape. Type locality is the Rio Guaporé, Mato Grosso, Brazil. Aquaristic imports are mostly from Peru.  Serrasalmus pingke from Venezuela was described from the Rio Apure. The holotype (54 mm long) is shown in MACHADO-ALLISON (2002); it has a […]

  • Acrossocheilus paradoxus

    9. November 2020

    Only rarely does the pretty barbel Acrossocheilus paradoxus reach us, which is native to China and Taiwan. It is a medium sized species; in the wild you usually find specimens up to 12 cm total length, but the record for this species is 22.5 cm. Such large animals look different, the head is longer and […]

  • Parotocinclus eppleyi

    6. November 2020

    One of the smallest loricariid species at all is Parotocinclus eppleyi, the Peppermint-Oto. The species is fully grown with a length of 3 cm (without caudal fin), but such animals can already be seen as xxl-format and are extremely rare. Usually the species, which is common in the upper and middle Orinoco, is 0.5-1 cm […]

  • Brochis splendens “Rio Negro

    6. November 2020

    Via Manaus we have been able to import splendid Brochis splendens. The Emerald Cat comes from a huge area, from Peru to the Pantanal in Brazil; based on the experience with other Corydoras it is more than likely that there are several species hiding behind the name “Brochis splendens”. But such things should be subject […]

  • Tanichthys “Gold Longfin“

    4. November 2020

    Since its first import in the 1930er years, the White Cloud Mountain minnow (Tanichthys albonubes) is available practically exclusively as offspring for the aquarium hobby. Nowadays, this is all the more true since the free-living stocks are considered highly endangered due to environmental pollution. However, the “simple” white cloud is not really bred by most […]

  • Serrasalmus humeralis

    2. November 2020

    The identification of many Piranha species is difficult. One of the earliest described piranha species and therefore with many taxonomic problems is Serrasalmus humeralis. Valenciennes was the first descriptor in 1850, but there is no question that he had received the type specimen, for which he states “Amazon” as the type locality, from Castelnau. In […]

  • Trichogaster leerii WILD – Borneo

    30. October 2020

    The pearl gourami (Trichogaster leerii, Trichopodus leerii) is one of the most popular aquarium fishes at all. It is probably not exaggerated if one assumes millions of individuals in aquariums all over the world. All these fish are bred ones. It is only little known that the pearl gourami belongs to the endangered species as […]

  • Pseudotropheus sp. “Acei” White Tail Ngara

    30. October 2020

    Where does a species start, where does the location variant end? This question is really difficult to answer for some groups of fish, e.g. killies and cichlids from Lake Malawi and Lake Tanganyika. In the case of Pseudotropheus sp. “Acei” from Lake Malawi, the species is not described scientifically. Mostly the light blue, yellow-fin “Acei” […]
