The red/blue Colombian tetra is a member of the Charicidae family native to South America. Its peaceful temperament and reflective body with a bright red tail make the species a favorite of beginning and expert aquarium enthusiasts.
According to LiveQuaria, a site which sells Colombian tetras, a planted aquarium of at least 20 gallons is ideal for housing them; driftwood and rocks help mirror their natural habitat to reduce stress. The Colombian tetra does best in tanks with high filtration and soft, slightly acidic water. Small offerings, such as freeze-dried bloodworms, brine shrimp, daphnia and high-quality flake foods, are well accepted by the species.
