  • 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 […]

  • Aulonocara Orange Blotched

    12. August 2021

    Everything there is to say about these wonderfully colorful cichlids has already been said about another breeding variety, the Aulonocara Dragon Blood: https://www.aquariumglaser.de/en/fish-archives/aulonocara-dragon-blood-2/ The Orange Blotched are now one of the most common Malawi cichlids on the market. No wonder: there is hardly a fish species, which shows such a variety of bright colors, like […]

  • Amatitlania (formerly Cichlasoma) nigrofasciata Marble

    9. August 2021

    The convict cichlid Amatitlania (formerly Cichlasoma) nigrofasciata is really not a novelty anymore: it has been kept and bred in aquariums since 1939. The first aquarium animals of this very widely distributed fish in Central America came from the lakes Atitlan and Amatitlan in Guatemala. The genus to which the convict cichlid currently belongs was […]

  • Betta splendens Hellboy II

    6. August 2021

    Some time ago we introduced a short-finned fighting fish breeding form (“Pla Kat”) of Betta splendens as “Hellboy”. (https://www.aquariumglaser.de/en/fish-archives/betta-splendens-pla-kat-hellboy-and-giant-halfmoon/). Now we have received Pla Kat under this name from Thailand again, but they differ from the first Hellboys in color and fins. The new Hellboys have a halfmoon tail fin, which means that when the […]
