Relevant Information:

The Neotropical auchenipterid catfish genus Auchenipterichthys includes four species. Auchenipterichthys thoracatus, formerly considered to be widely distributed throughout the Amazon River basin, is found to be restricted to the upper Madeira River basin. The widespread Amazonian species that had been misidentified as A. thoracatus is, instead, A. coracoideus; a species that also occurs in the upper Essequibo River. Auchenipterichthys longimanus, the most widely distributed species of the genus, is found through much of the Amazon and Orinoco River basins. The fourth species of the genus, A. punctatus (and its junior synonym A. dantei), is found in the upper portions of the Orinoco and Negro River basins in Venezuela and the central portions of the Amazon River basin in Brazil. (Ferraris et al 2005). Aquarium Care: Good community catfish with normal sized patrons but not to be trusted with small Tetras for instance, which will be picked of at night on its twilight patrols. Breeding: This family practice internal fertilization with the female depositing the fertilized eggs on aquatic vegetation with no care of the eggs shown. An unsuccessful breeding report states that the male swims behind the female and they suddenly lock their pectoral, female's adipose and caudal fin. They speed around the tank and are oblivious to anything around them. After this confrontation they break apart and fall to the aquarium floor where they sit for a couple hours in a "dazed" condition. Diet: Can be fed most aquarium fare such as good quality flake, white worm, tablet and pellet foods and frozen foods such as bloodworm. Better to feed at lights out until they get accustomed to the daytime feeding regime when they may very well join in.
