Relevant Information:

This widespread Amazonian species, that had been misidentified in the past as A.thoracatus, and is instead A.coracoideus; a species that comes from the waters of the Amazon River basin and the Araguaia River in the the Tocantins basin while Auchenipterichthys thoracatus is found in the upper Madeira River basin. 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.
