  • Corydoras caudimaculatus Wild

    21. August 2020

    From the Brazilian state of Mato Grosso, more precisely from the upper Rio Guaporé, comes the pretty Corydoras caudimaculatus, which reaches 5-6 cm in length. C. caudimaculatus is the most round-nosed and high-backed species of the “tail-spotted armored catfish”, which all have a similar pattern, but without being closely related to each other. The evolutionary […]

  • Megalechis thoracata

    19. August 2020

    The Port Hoplo Megalechis thoracata – maybe the synonym (now invalid) name Hoplosternum thoracatum is more familar to some readers – is one of the earliest aquarium fish at all. The fish has only one real disadvantage: the maximum size, which is about 15 cm (or sometimes even larger). However, the species has a comparatively […]

  • Hypancistrus sp. L500

    7. August 2020

    In northern tributaries of the Amazon, namely the Rio Nhamunda (L475), the Rio Padauari (L499) and the Rio Uatumá (L500), there are very similar Hypancistrus, which have a relatively stocky body in common. In colour they resemble very much the Hypancistrus furunculus (L199) from the upper Orinoco. All four Hypancistrus are extremely variable in colour, […]

  • Corydoras sterbai WILD

    5. August 2020

    The magnificent Corydoras sterbai is probably known by every aquarium child. As one of the most beautiful Corydoras, C. sterbai belongs to the standard offer of the pet shop and is bred in large quantities; there is also an albinotic breeding form which does not occur in the wild. However, wild Corydoras sterbai from the […]

  • Balroglanis schultzi (formerly Centromochlus s.)

    3. August 2020

    The driftwood catfishes enjoy an increasing popularity, since it succeeds regularly to reproduce them. All species have – as far as known – an internal fertilization, the females spawn later without the presence of a male. Most driftwood catfishes are active at night or twilight. Many species are known to hunt land insects that have […]

  • Corydoras aurofrenatus

    31. July 2020

    For the first time, we have this beautiful Corydoras, that was described already 1903 from Paraguay, as bred ones in stock. However, there is no possibility to distinguish the Corydoras aurofrenatus from C. ellisae, which was also described from Paraguay in 1940. Therefore both species were synonymised by Axenrot and Kullander in 2003, the name […]

  • Corydoras sp. “Peru”

    27. July 2020

    Sometimes it is coincidence that determines whether a fish species can establish itself in the hobby. In the case of this Corydoras sp. Peru, a Corydoras fan noticed the fish when visiting a wholesaler; they were so-called by-catches that had been sorted out. Unfortunately, the wholesaler could not remember exactly where the animals originally came […]

  • Ancistrus claro

    20. July 2020

    One of the smallest Ancistrus species is Ancistrus claro, which was known as LDA 8 before its scientific description. The catfish originates from clear water streams with a strong current in the upper part of the Rio Paraguay-Paraná river basin and becomes at most 6-8 cm long. The sexes are not quite as easy to […]

  • Synodontis nigriventris

    10. July 2020

    The most popular squeaker catfish (Synodontis) by far is the upside-down catfish (Synodontis nigriventris) from the Congo. It is not the only species of the genus that often (by no means always) swims on its back, but it remains small (under 10 cm) by squeaker catfish standards and is one of the most peaceful representatives […]

  • Pseudohemiodon laticeps

    10. July 2020

    Pseudohemiodon laticeps from Paraguay belongs to the longest known mouth-breeding Whiptail Catfish in the hobby, even if this large (up to 35 cm) species with its species-specific broad, triangular head was confused for a long time with the very similar, narrow-headed species P. platycephalus from Brazil. Mostly one sees both species in a fawn-brown colouring […]
