One of the most recognizeable species of Tetra in the aquarium trade, Neon Tetras are also one of the most popular species. These fish are brightly colored, having light blue coloration on their backs over white bellies. The most striking feature of these fishes is the iridescent blue stripe running horizontally from the nose to the base of the tail, accompanied by a red stripe underneath which runs about halfway along the body. Neon Tetras are native to Brazil, Peru and Columbia where they can be found in forested areas and slow-moving blackwater tributaries. These fish are commercially bred in large numbers and wild-caught specimens are rare in the aquarium hobby.
