  • Brienomyrus brachyistius

    18. February 2019

    We obtained from Nigeria a species of mormyrid which we haven´t seen for years: Brienomyrus brachyistius. This comparably small species (maximum length reported is 17.cm, usually the fish becomes 10-12 cm long) is a close relative to the species B. niger, which we were also able to import again (see http://www.aquariumglaser.de/en/brienomyrus-niger_de_1152.html). The intelligent and playful […]

  • Gnathonemus petersii – Peters’ elephantnose fish

    20. August 2018

    Most often this bizarre mormyrid is kept as a single specimen. This is due to the fact that small groups of this fish most often don´t do well in a long time sight and they can perform mobbing against each other even to death. However, in the wild these up to 30 cm long, but […]

  • Mormyrus rume

    25. May 2018

    We obtain comparatively often this interesting mormyrid from Nigeria. Sadly systematics of Mormyrus are confusing. According to the latest scientific state of the art currently five species of Mormyrus occur in Nigeria, among them M. rume. The shape of the snout is the best feature to distinguish the species. Formerly the fish portayed here was […]

  • Chitala blanci

    28. June 2017

    The Asian featherbacks, which have a well developed dorsal fin, have been placed in the genus Notopterus for a long time. Nowadays the genus Notopterus is seen monotypic (it contains only the single species N. notopterus) and the high-backed forms have been placed in another genus, namely Chitala. Currently we have the very attractive species […]

  • Pantodon buchholzi

    12. July 2016

    If there would be a Top Ten ranking on the most extraordinary species of freshwater fish of the world, this species would appear for sure: the African Butterfly fish, Pantodon buchholzi. We have this strange animal – it becomes about 10 cm long – always in stock. Our specimens originate from Nigeria. Pantodon can really […]

  • The possibly rarest fish in the world lives in Aquarium Glaser´s fishhouse

    20. February 2015

    The term “rare” is – as anybody knows – much a matter of subjectivity. As far as small species of fish are concerned, “rare” can mean that they are only rarely collected, or that they are hardly ever exported or imported, respectively, or that they are hardly ever kept in aquaria. “Rare” hardly ever means in […]

  • Scleropages jardinii and S. leichardti

    22. December 2014

    The Bony tongues (Osteoglossidae) are real old high aristocracy among the recent fish species. They are witnesses of the ancient super continent of Gondwana, which included the recent parts of Africa, India, South America, Antarctica, and Australia. About 150 million years ago this super continent began to break. The Bony tongues drifted away from each […]

  • Mormyrus rume

    Mormyrus rume

    24. September 2014

    We received a species of bred fish from Singapore which is usually only traded as wild collected ones: Mormyrus rume. Currently the genus Mormyrus contains 24 species and subspecies. The determination is a very difficult task. Moreover, juveniles look totally different to adults. We obtained bred specimens of a species of Mormyrus from Singapore under […]

  • 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 […]
