  • Atyopsis moluccensis

    12. April 2021

    Among the numerous shrimp species that have gained a firm foothold in the hobby are two larger species of fan shrimp, namely Atyopsis moluccensis, the Moluccan mountain rock shrimp from Southeast Asia, and Atya gabonenis, the Gabon giant fan shrimp from West Africa. They grow relatively large (A. moluccensis approx. 9 cm, A. gabonensis approx. […]

  • Rineloricaria heteroptera

    9. April 2021

    From Brazil we received beautiful whiptail catfishes, which we thought at first sight to be Rineloricaria lanceolata, a species with a very wide distribution. The high proportion of reddish animals was striking.  The majority of the fish are small, 3-4 cm long and marked like R. lanceolata, but there are a few adult specimens among […]

  • Corydoras cf. armatus “Spotted Putumayo“

    9. April 2021

    From Colombia we received a nice Corydoras species, which threw us into some confusion during identification. They were sent as C. armatus, a species described from the Rio Huallaga, a right-bank tributary of the Rio Maranon (the larger of the two headwaters of the Amazon) in Peru.  C. armatus is a conspicuously high-backed species with […]

  • Epalzeorhynchos kalopterum

    7. April 2021

    The Flying Fox, Epalzeorhynchos kalopterum (Epalzeorhynchos is neuter, so if the species name is an adjective – as in this case – it must end in the Latin neuter suffix -um), originates from Indonesia, Malaysia and Thailand, where it is a resident of flowing waters that carry deep dark brown black water. They are probably […]

  • Poecilia velifera Silver

    6. April 2021

    Silver mollies are among the most popular livebearers. Most of the silver mollies in the trade are a breeding form of Poecilia latipinna. Since the species Poecilia latipinna, P. sphenops, P. mexicana and P. velifera can be crossed and color characteristics and certain fin shapes (e.g. lyratail) are transferred to the hybrid young, the desired […]

  • Xiphophorus hellerii “Yucatan 2”

    1. April 2021

    From a German breeder we received this extraordinarily attractive wild form of the swordtail. Unfortunately we could not find out where exactly and by whom these animals were collected. It could only be determined that they were originally brought from Yucatan (Mexico). As a distinction to the completely different looking X. hellerii “Yucatan” (see https://www.aquariumglaser.de/en/fish-archives/xiphophorus_hellerii_yucatan_en/) […]

  • Mikrogeophagus ramirezi wild

    1. April 2021

    Because of the enormous popularity of the butterfly cichlid or blue ram (Mikrogeophagus ramirezi), there are mainly offspring and breeding forms on the market. Also the wild-colored offsprings differ clearly from the wild species: they are considerably larger (4-5 cm body length without caudal fin compared to 2-3 cm with wild-caught fish) and at the […]

  • Freshwater rabbitfish

    1. April 2021

    The rabbitfishes of the genus Siganus are well known to marine aquarists. They are beautiful animals that usually grow to 15-30 cm in length and eat mainly vegetable food. Until now no freshwater species of the genus was known, only Siganus vermicularis is regularly found as juvenile in the brackish water of river mouths. Now, […]

  • Oligolepis acutipennis

    31. March 2021

    Oligolepis acutipennis is one of the most widespread gobies of the Indo-West Pacific. The species, which can grow up to 15 cm long, is distributed from South Africa via East Africa, the Persian Gulf, Madagascar, Indonesia and along the entire coast of Southeast Asia to Japan. From this wide distribution one can easily conclude that […]

  • Corydoras reynoldsi & Corydoras tukano

    29. March 2021

    Corydoras reynoldsi is a pretty cory catfish that has been described in 1960. It was collected in the Caquetà province, eastern Colombia. It remained unknown in the hobby quite long, as this area is far away from the usual collecting areas. In 1997 the cory enthusiasts became aware of another, quite similar species of Corydoras […]
