 The following is a selection of few of the many marine cleaner species.Commonly studied cleaner fish are the cleaner wrasse of the genus "Labroides" found on coral reefs in the Indian Ocean and Pacific Ocean.Neon gobies of the genera "Gobiosoma" and "Elacatinus" provide a cleaning service similar to the cleaner wrasse, though this time on reefs in the Western Atlantic, providing a good example of convergent evolution of the cleaning behaviour.
