Relevant Information:

Similar to Pseudopimelodus but the head is very large and flattened and is the only species in this genera. Dorsal fin short and the caudal fin is rounded. The juveniles look similar to the Chaca genera from Asia and like them are very predatory. Aquarium Care: Not to be kept with fish that are too small as they will be eaten, better to be kept on their own or with large non-aggressive species. Would need a large aquarium as this species grows to 70cm. SL. Has been bred in the aquarium. Diet: Live foods such as earthworms and frozen foods.

Common Name:
