The Redtail Cat has a broad head and body that tapers towards the tail. It has a dark black body, white underbelly, and a bright red tail.
The Redtail Cat can grow impressively large in an aquarium setting and should be given plenty of room to swim. Due to its size and high energy, this fish should be kept with larger tank mates. Besides the minimum tank size of 300 gallons, rocks, plants, and large driftwood should be used to enhance and simulate a natural environment. Since the Redtail Catfish is a highly active fish, a tightly covered aquarium should be used to prevent it from jumping out of the tank. They mature into a very heavy fish and should be maintained in a reinforced aquarium.
Redtail Cats breed using external fertilization after laying their eggs. Breeding in an aquarium setting is rare.
Feeding the Redtail Cat is not difficult due to the fact that it is not a picky eater. In the wild, this fish will eat fish and crustaceans. In the aquarium setting, assorted worms, frozen foods, sinking catfish pellets, and dry foods will provide the proper nutrition.
