19. Halfbeaks (17)

  • Dermogenys siamensis (D. pusilla)

    11. March 2019

    The systematics of the widespread, small halfbeaks from South and Southeast Asia are complicated. A first revision of the genus by Mohr in 1936 summarized many previously described species under the synonymy of D. pusilla. This was followed by Brembach in 1991; the name D. pusilla was then used in the broadest sense. It was […]

  • Potamorrhaphis labiatus

    31. August 2018

    The slender freshwater needlefish from South America are much sought for by specialists. Many years only one species was mentioned in the aquarium literature, namely Potamorrhaphis guianensis. This species really exists and is said to be fairly wide spread in South America. But it seems that the needlefish we obtain from Peru currently belong to […]

  • Nomorhamphus liemi 

    3. November 2017

    This wonderfully coloured halfbeak originates from the island of Sulawesi ( = Celebes) where it occurs in the southern half; it is endemic in the Maros highlands. In contrast to the closely related genus Dermogenys the upper and the lower jaw are approximately equally long (thus the generic name). In some species, however, is seems […]

  • Zenarchopterus dunckeri

    21. March 2016

    The wonderful, large halfbeaks of the genus Zenarchopterus are only very rarely offered, because the animals are very shy during the acclimatisation. When they panic they often hurt themselves seriously. So we are very proud that we were able to import successfully a small group of fully grown specimens of the species Zenarchopterus dunckeri from […]

  • Zenarchopterus dunckeri

    21. March 2016

    There are 20 valid species in the genus Zenarchopterus, all of them occuring along the Pacific coast of tropical Asia. The maximum length of Zenarchopterus is around 15 cm, only a few species are recorded to reach a greater length, most of them stay smaller. The species are very similar to each other and the […]

  • Nomorhamphus celebensis

    16. October 2015

    Most of halfbeaks of the genus Nomorhamphus originate from Sulawesi (formerly known as Celebes). Some species, like N. ebrardtii or N. rex, are traded usually as wild collected ones, others, among them N. liemi, are occasionally also available as bred ones. A species that occurs hardly ever in the trade is the Black Halfbeak, Nomorhamphus […]

  • Nomorhamphus liemi and N. ebrardtii

    22. December 2014

    The pretty halfbeaks of the genus Nomorhamphus reach us usually as wild collected fish from Indonesia. They originate from the island of Sulawesi (formerly: Celebes) where they inhabit preferably running waters. They like to feed very much on insects from the water surface, but they also take readily dried or frozen food. Males become usually […]

  • Potamorrhaphis guianensis

    26. September 2014

    The needlefishes (Belonidae) are mainly marine fish. But there do exist three genera with a total of eight species in South America that live exclusively in freshwater. Among them the genus Potamorrhaphis is the most specious one: currently four acceoted species are known. Potamorrhaphis can attain a maximum length of about 30 cm. Astonishingly these […]

  • Dermogenys siamensis

    3. June 2014

    These tiny “pikes” are real wonders of nature. The fish become only 4-5 cm long. They obtained their popular name “halfbeak”, because the upper part of the beak is only half as long as the lower one. In Dermogenys this upper half of the beak is movable. It is used by the animals to catch […]

  • Hemirhamphodon phaiosoma

    17. September 2013

    For the first time ever we could import this very beautiful halfbeak from Indonesia. The halfbeaks of the genus Hemirhamphodon are adapted to blackwater in the wild. Thus they need – at least for the time of acclimatisation – very soft and acidic water. Maximum length of the species is around 6 cm (male), females […]
