Labroides dimidiatus

Labroides dimidiatus, commonly known as the cleaner wrasse, is a small marine fish found in coral reefs. It plays a crucial role in the ecosystem by cleaning other fish, removing parasites and dead tissue from their bodies. This behavior benefits both the cleaner wrasse and its "clients," as the fish get rid of pests and the cleaner gains food. Recognizable by its vibrant coloration—typically blue with a stripe down its side—it is popular in the aquarium trade. Its symbiotic relationship highlights the importance of mutual cooperation in marine environments.
