Tetra

Tetra is the common name of many small freshwater characiform fishes. Tetras come from Africa, Central, and South America. There are many species including the neon tetra (Paracheirodon innesi), these are hugely popular due to being brightly colored and easy to keep in captivity. They make an attractive addition to a peaceful aquarium. Ideally, keep six or more fish of the same tetra species in the aquarium with moderate lighting for them to thrive.
