  • Oxydoras niger

    With a maximum length of 1 meter Oxydoras niger belongs to the largest species of thorny catfishes. Nevertheless it is a very peaceful species and therefore quite attractive for owners of very large aquariums, show aquariums and zoos. Fully grown these fishes are uniformly black (this is exactly what the species name “niger” = black […]

  • Platysilurus mucosus

    15. June 2022

    Predatory catfishes exude a special fascination to many a catfish lover. Unfortunately, many species simply become too large for permanent care in a normal sized home aquarium. However, there are also species that grow to only 20-30 cm in length and for which it is therefore not necessary to flood the entire basement to meet […]

  • Platydoras armatulus

    20. May 2022

    The snarling zebra catfish – this is how Platydoras armatulus could be popularly called. However, it is actually called the striped raphael catfish. All spiny catfish can make distinct growling or croaking sounds when taken out of the water. They vibrate their whole body. Presumably this serves as a defense against enemies. But even without […]

  • Batrochoglanis sp. Venezuela

    Something is happening with the South American bumblebee and frog catfishes! In former times they were assigned to the long-whiskered catfishes (Pimelodidae), today they are placed in an own family, the Pseudopimelodidae. Often in the trade are the striking yellow-black marked, only 3-8 cm large South American bumblebee catfishes (Microglanis, 23 species), and the similarly […]

  • Tatia musaica/ Centromochlus musaicus

    23. March 2022

    When the first black and white “Tatia” appeared in the ornamental fish trade some years ago, they were celebrated as a sensation. (see https://www.aquariumglaser.de/en/fish-archives/centromochlus_sp_ninja_en/ and https://www.aquariumglaser.de/en/fish-archives/tatia_musaica_en/).

  • Tatia galaxias

    11. February 2022

    The cute Tatia catfishes are quite popular in the hobby. Keepers put up with the fact that you can hardly see them outside feeding times, because they are extremely addicted to hiding. But they make up for it with their pretty coloration and good breedability. Tatia galaxias comes from the Orinoco river basin in Colombia […]

  • Nemadoras elongatus

    31. January 2022

    The thorny catfishes are a very interesting and diverse group of catfishes. We were able to import from Peru the slender species Nemadoras elongatus, which can reach a total length of about 12-15 cm. At first sight the fishes remind very much of the Hassar species, which they also resemble in behavior. They are peaceful […]

There were all kinds of debates about its name, for a long time it sailed under Pseudopimelodus zungaro or Paulicea luetkeni.

    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 […]
