This cleaner wrasse is found in many coral reef environments in the Indo-Pacific, where it feeds on tiny crustacean-like parasites that live on the surface of other fish. This wrasse will set up cleaning stations in a certain area of the reef, where other fish will come and allow the wrasse to eat these parasites from their bodies. This type of relationship is called mutualism, in which both the cleaner wrasse and the fish it cleans benefit from the interaction.
