The green and black neon tetras are distinct species (the latter belonging to an altogether different genus, in fact) and not color varieties. The cardinal tetra, also sometimes called the red neon, is a very similar species and is often confused with the true neon tetra. Hyphessobrycon innesi, on the other hand, is an obsolete synonym for P. innesi, the neon tetra itself.
