  • Abramites hypselonotus

    27. August 2021

    The marbled headstander is perhaps the most unusual of all headstanders. This beautiful fish grows to about 15-20 cm in length and is hard to mistake because of its high body shape. There is only a second Abramites species, A. eques, but it has never been imported alive. It lives exclusively in the Rio Magdalena […]

  • Pseudacanthicus sp. L79

    27. August 2021

    This very flat Pseudacanthicus from the Rio Tocantins belongs to the rarest L-catfishes on the market. Even before the export ban by the Brazilian authority IBAMA, which was lifted only recently, the fish came to us only very sporadically. L79 certainly grows over 20 cm long, but exactly how big is unknown. Our animals are […]

  • Poecilia wingei Blue Star

    25. August 2021

    Poecilia wingei is widely distributed in the hobby after its best known local variant as Endler´s Guppy. It remains much smaller than the normal Guppy and is very popular with many aquarists because of its graceful body shape.  Just as with the common Guppy, numerous local forms can be observed with P. wingei. The ancestor […]

  • Sciaenochromis fryeri

    23. August 2021

    Many rock dwelling cichlids (mbunas) of Lake Malawi live isolated on certain rocky shores. These are often miles away from other rocky biotopes, so geographic isolation leads relatively quickly to local color variations. Other cichlids of the lake, such as Sciaenchromis fryeri, are not bound to specific biotopes and occur accordingly throughout the lake. Although […]

  • Ageneiosus magoi

    20. August 2021

    Males of all dolphin catfishes (Ageneiosus) develop huge dorsal fin spines and a penis-like mating organ at spawning time, also strange tooth-like looking papillae on the posterior margin of the upper jaw. They use the dorsal fin spine to clamp females for mating, and fertilization occurs internally. After spawning, the dorsal fin spine is shed […]

  • Wertheimeria maculata

    20. August 2021

    Wertheimeria maculata belongs to the strangest thorny catfishes. You don’t see this on the relatively inconspicuous juveniles with their 6-8 cm length, but it is nevertheless so. The first thing that catches your attention is the really high price that is demanded for them. This is due to the fact that these fish are local […]

  • Mylesinus paucisquamatus

    19. August 2021

    A few weeks ago we introduced you to a new pacu, which we received as Tometes kranponhah. At that time we thought the animals originated from the Rio Xingu. (see https://www.aquariumglaser.de/en/fish-archives/tometes-kranponhah-2/)  In the meantime, further correspondence with our supplier revealed that the animals did indeed come from the Rio Tocantins. We have received another shipment […]

  • Platy Wagtail Pointed Tail

    16. August 2021

    The “pointed tail” mutation, in which the middle caudal fin rays are elongated, appeared relatively late: the first specimens appeared on the market in the 1980s. It originated in the Southeast Asian large-scale breederies. The characteristic, which first appeared in the Platy (Xiphophorus maculatus), can also be transferred to other Xiphos, but the pointed tail […]

  • Corydoras schwartzi

    13. August 2021

    This well known, but still beautiful Corydoras originates from the Rio Purus system in Brazil. It was named in honor of the exporter Willy Schwartz. In Corydoras schwartzi, which belongs to the stocky, round-headed members of the genus, the dorsal fin is marked very slightly differently in each animal, the coloration of the spine ranges […]

  • Acanthicus sp. L155 Furo Maguari

    13. August 2021

    Acanthicus hystrix is one of the great myths in the literal sense. With a length of almost one meter it is one of the largest loricariid catfishes at all. In addition, the species, which was already described in 1829, is extremely prickly: “hystrix” means “porcupine”!  Unfortunately, the specimen on which the description of this species […]
