This behavior mutually benefits the fish and the environment that they live in as they clean the dead tissues in coral reefs and, in the process, feed on live tissues. The areas where these wrasses operate are known as 'cleaner stations'. When another marine animal approaches the coral reef they will visit these cleaner stations. Cleaner wrasses live at cleaning stations and these cleaning stations are occupied by different types of cleaner wrasses, including a group of youths, a pair of adults, or a group of females lead by a dominant male. When visitors approach the cleaning stations, the cleaner wrasses welcome them by performing a dance-like motion in which they "clean" the visitor (known as a 'client') by getting rid of parasites on the fish's body.
