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 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 […]
Among the largest loricariid catfish are some of the wood-eating Panaque species. Panaque schaeferi is one of them, the species will certainly grow to about 60 cm long. Since P. schaeferi was described on the basis of adult specimens, the assignment to the young animals belonging to it has never been scientifically confirmed. However, it […]
There are three beautiful, very closely related, small (4-5 cm) armored catfish species on the Guyana Shield in South America, which look so similar to each other that they have already been seen as synonymous with each other in the past: Corydoras bondi, C. coppenamensis and C. sipaliwini. However, most lovers of Corydoras share the […]
The tiger pleco was already imported and presented in 1988; since then, unfortunately, no scientist has yet taken a closer look on the beautiful animals imported from Rio Tocantins in Brazil for the hobby; therefore, this relatively small, maximum 12 cm long, peaceful loricariid catfish still has no “correct” name, but has to be content […]
One of the most beautiful squeaker catfish (Synodontis) comes from the Congo: Synodontis decorus. The slender species grows about 20-30 cm long and is relatively peaceful. One must always consider that all squeaker catfish have a hierarchy among each other, where “social biting” is absolutely necessary and not alarming, since it only comes to superficial, […]
We receive only very rarely imports of one of the unusual and stress-prone Leptodoras species. These thorny catfish are extraordinarily elongated and apparently live in flowing waters, while many other thorny catfish – think of the Platydoras, Agamyxis etc. which are common in the hobby – are more at home in dead wood or leaves […]
Until recently, two genera of closely related whiptail catfish were distinguished according to anatomical features: the relatively short-nosed Sturisomatichthys with four described species and the relatively long-nosed Sturisoma with over 15 species. All species are popular aquarium fish because they are attractive and easy to breed. Unlike most other loricariid catfish they do not breed […]
Again and again we receive imports of Corydoras from the upper Rio Negro area, which differ in details from the well known Corydoras adolfoi, C. duplicareus, C. imitator, C. serratus & Co. It is difficult to classify them in such cases. Are these only colour variations that occur in large numbers somewhere? Are they geographically […]
For a long time it was believed that there were only two species of electric catfish, namely the widespread Malapterurus electricus and the Congolese M. microstoma. Then two independent revisions of the genus appeared practically at the same time, one by Roberts (2000) and one by Norris (2002), which drastically increased the number of species, […]
