The Red Tail Barracuda is an ominous-looking fish with a long, slender, silver body and a bright red tail. The most distinguishing characteristic of this fish is the large, sharp teeth that are easily seen. Often referred to as the Freshwater Barracuda or Spotted Cachorro, this fish is a Characin related to both tetras and the piranha.

A 70 gallon or larger aquarium that is well established is ideal for this species. Provide the Red Tail Barracuda with driftwood and floating plants. There should be plenty of open swimming areas. Maintain a neutral to slightly acidic pH, and soft water. A vicious predator, the Red Tail Barracuda should only be housed with other more aggressive predacious fish of similar size. Ideally, it is best to not place this species with territorial species of Cichlids.

The breeding habits of this species are unknown, and the Red Tail Barracuda has yet to be spawned in the home aquarium.

The Red Tail Barracuda is a carnivore and should be fed a variety of live foods such as small fish and crustaceans.

Ideal tank mates include: Similar sized predators, similar sized, miscellaneous fish, Plecos and some Scavenger Catfish.
