11. Gymnotiformes: Knifefishes of the New World (23)

  • Sternarchorhynchus aus Peru

    Sternrachorhynchus from Peru

    28. July 2014

    This week we introduced to you already a species of knifefish from Peru: Brachyhypopomus brevirostris (see http://www.aquariumglaser.de/en/news.php#1122). The odd Sternarchorhynchus, which is theme of this newsletter, originates also from Peru, but belongs to a different family, eg the Apteronotidae. The number of described species of Sternarchorhynchus has risen enormously in the past few years. Up […]

  • Brachyhypopomus brevirostris

    23. July 2014

    Knifefishes occur in Africa, asia, and South America. However, the knifefishes from the Old World and the knifefishes of the New World are not closely related to each other. From an aquarists point of view all knifefishes are very beautiful to look at. They are elegant swimmers. The extraordinary swimming style – they rather glide […]

  • Adontosternarchus clarkae

    19. November 2012

    Marbled Dwarf Ghosts. The most important species New World Knifefishes or Ghosts in the ornamental fish trade are without any doubt the Black Ghost (Apteronotus albifrons) and the Brown Ghost (A. leptorhynchus). We have both species in stock on a regular basis, the Black Ghost both as wild collected from Colombia/Venezuela and bred ones, the […]

  • Adontosternarchus nebulosus

    23. August 2012

    For the first time ever we can offer this very nice and comparatively small species (around 20 cm) of knifefish. The species has been described scientifically only in 2007; our specimens originate from Peru. Available in limited numbers only! For our customers: the fish have code 202794 on our stocklist. Please note that we exclusively […]

  • Compsaraia samueli

    Compsaraia samueli

    7. February 2012

    Only a few specimens of one of the most remarkable knifefishes of the New World reached us from Peru: Compsaraia samueli. The males of this “pelicano knifefish” develope grotesque long snouts. The males are absolutely intolerant against each other. They fight with mouths wide open in a manner that is known from fighting male deer. […]

  • Eigenmannia trilineata

    29. August 2011

    We received wonderful specimens of Eigenmannia from Guyana. They show three black longitudinal stripes on a smokey ground. This fits perfectly to the pattern described in the species E. trilineata, which is known so far only from the Paraguay-Paraná system (Argentina, Brazil, Paraguay, Uruguay). May that be as it is: Eigenmannia are fantastic aquarium fish […]

  • Adontosternarchus clarkae

    23. August 2011

    This small (maximum length up to 20 cm) knifefish from Venezuela is only rarely imported and again we were able to obtain only a few specimens. It is a very nice and peaceful species. The genus Adontosternarchus currently comprises four accepted species which can be distinguished best by differences in the head profile in combination […]

  • Apteronotus leptorhynchus GOLD

    11. January 2011

    A very special knifefish reached us currently from Colombia: a golden Apteronotus leptorhynchus! The species is widespread and common in Colombia and we have the “Brown Ghost” regularly stocked; but this is the first time ever that we became aware of a specimen with such an unique coloration. For our customers: the animal has code […]

  • Parapteronotus bonapartii

    30. September 2010

    There is a lot of movement in the South American Knifefishes. Science has put an eye on these fascinating, electrical fishes and so a flood of new species descriptions and revisions has been published quite recently. Most genera and species are only weakly electric and use the electric pulses for orientation and communication. However, the […]

  • Newly in: Electric eels

    29. September 2010

    Wonderful Electric eels (Electrophorus electricus) from Peru reached us lately. The animals are 40-50 cm long. The three of them are astonishingly peaceful among each other and feed  readily. The fish have nice pale spots on the flanks, which are typical for specimens from Peru  and which make the fish even more attractive. For our […]
