The shifter catfish (Synodontis nigriventris) is the smallest member of the genus Mochocidae. The relatively small size and unusual normal body position make this fish interesting for keeping in a room aquarium.
Hoplosternum thoracotum
Hoplo Catfish (Hoplosternum thoracatum) — Species Overview
The Hoplo Catfish, known scientifically as Hoplosternum thoracatum (Valenciennes, 1840), is one of the most fascinating armoured catfish in the hobby. A member of the family Callichthyidae, it stands out not only for its robust, plated body but also for a remarkable physiological trait: the ability to breathe atmospheric air through a specialised intestinal respiratory organ. In my years of fishkeeping experience, this species has consistently proven to be both rewarding and surprisingly engaging to observe.
Bunocephalus bicolor
Bunocephalus bicolor is another fish that is part of the group that most amateurs call simply catfish. This is facilitated by a certain body shape and the presence of whiskers.
Ancistrus
The ancistrus catfish is quite a funny creature. Unlike some other catfish, the ancistrus is constantly on the move and likes areas with a fast water current.
