Description
This fish has also been placed in its own family, Calophysidae.[2]
This species reaches 40 centimetres (16 in) SL and originates from the Amazon and Orinoco basins.[3] This species is reported to commonly attack the fishes caught in fishermen’s nets and seines as well as those hooked on trotlines or gaffed.[3]
This fish species is a smaller Pimelodid, and may be appropriate for a large aquarium. It is an adaptable and hardy species. Tankmates should be chosen with great care as this fish has the ability to bite and tear off pieces of flesh,[2][4] although many who have actually kept the fish report no apparent signs of aggression.[5]
