Redtail Catfish Tropical Fish Learn all about the Redtail Catfish's feeding habits and food types, its behaviour, its origins, its natural habitats, is it male or female, breeding advice and information, suitable tank mates, its sizing and growth range, minimum tank size, water PH and more. Use our fish community creator tool to plan your tank set up and ensure that the Redtail Catfish is the right fish for your aquarium.

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.
