Notes: The Neon Tetra is the most popular aquarium fish in the world. This fish is not to be confused with the similar looking Cardinal Tetra. Water quality is a MUST when keeping these fish, since these are very fragile fish. Keep these fish in schools of at least four. These fish are sensitive to light, so a heavily planted aquarium is a must. Feed these fish quality flake foods, or assorted live foods like brine shrimp
