The Cleaner Wrasse is a small, colorful fish found in coral reefs across the tropical and subtropical oceans. They are known for their unique behavior of cleaning parasites and dead skin off larger fish, which helps maintain the health of their clients. These fish typically grow to about 4 inches in length and have a distinctive blue and yellow coloration. Cleaner wrasses play a crucial role in the ecosystem by promoting the well-being of various fish species. Their cleaning stations attract larger fish, which seek their services. This mutualistic relationship benefits both the cleaner wrasse and the client fish, as the wrasse receives food while the larger fish enjoy improved health.
