Jump to next section Species Information
Size 500mm or 19.7" SL. Find near, nearer or same sized spp.
IdentificationBody somewhat elongate and head broad. Eyes superior. Barbels flattened with maxillary pair extending past the end of the adipose fin. First dorsal and pectoral fin rays are 'soft'. Number of spots on the body varies greatly between populations.
General RemarksThis fish has at times been placed in its own family, the Calophysidae. Although it externally looks much like other pimelodids its unique dentition, different positioning of the fins from other pimelodids, and reduced and encased swim bladder make it a distant relative of the other pimelodids.

Jump to next section Husbandry Information
FeedingAn adaptable carnivore as the common name, 'vulture catfish' applies.
FurnitureComfortable in almost any environment, including sturdy planted aquaria, provided it has sufficient hiding places.
CompatibilityA true scavenger that is also a vicious predator. Its unique dentition allows it to bite other fishes and remove chunks of flesh. Often attacks the catch of fishermen while they are hooked or netted. This ability has given the name bagre matchete (machete catfish) in Venezuela and Colombia. They are so vicious in their attacks that they sometimes stay attached even when their prey is removed from the water.

Tankmates should be chosen with great care. While it appears this fish mainly attacks wounded fishes, it certainly has the ability to rip any tankmate to shreds should it desire to do so.
Suggested TankmatesArmored loricariids and doradids, larger fish such as cichlids.
BreedingUnreported.
