Noronha wrasse

The Noronha wrasse (Thalassoma norohanum) is a species of wrasse native to the western Atlantic Ocean off the coast of Brazil and nearby islands, where it inhabits coral reefs from the surface to 60 m deep, though mostly much shallower, between 2 and 5 m. Younger individuals act as cleaner fish. This species can reach 13.3 cm in standard length. It can also be found in the aquarium trade.
