Redtail Catfish

Phractocephalus hemioliopterus

The Redtail Catfish is a large predator which has no place in the home aquarium trade. This fish will grow up to 100cm in the aquarium, and even bigger in nature. Although older fish are not especially active, they will require an aquarium 400cm (13.5 feet) long as a minimum to allow a humane level of swimming room. No respectable shop should be selling these fish to the general public.

This fish is excluded from the Compatibility Checker as it is unsuitable for community aquariums or may require expert care.

Family Pimelodidae | Synonyms Silurus hemioliopterus, Phractocephalus bicolor, Pirarara bicolor | Other names Red Tailed Catfish | Origin South America; Amazon and Orinoco River basins | Natural Water Conditions pH 5.5-7, medium | Natural Habitat Deep rivers and pools
