The Smith's Blenny is also known as White's Blenny Smith's Blenny, White Blenny or Disco Blenny. The body of the fish is predominantly blue, with the black stripe that starts at the chin, and continues across the eyes and then along the dorsal fin. It is most likely to thrive in aquariums if it is provided with live rock in a 10 gallon or greater aquarium. Live rock offers spots to hunt and eat small crustaceans, as well as areas to conceal. It's not typically aggressive unless tankmates have the same shape as it does. The fangs of the White Blenny Smith are for biting an aggressive fish.   The Smith's Blenny diet is comprised of chopped crustaceans and vitamin-rich brine shrimp and frozen food preparations designed for herbivores.
