Although referred to simply as a “Neon,” the Black Neon is quite distinct from the “true” Neon Tetra (Paracheirodon innesi). It is, nevertheless, neonlike in that it possesses an iridescent golden-green line that runs all the way from the head to the base of the caudal fin. This contrasts sharply with the bold black line that runs below it. Such coloration makes a large shoal of Black Neons a truly impressive sight.
