What is cleaner wrasse?

Cleaner wrasse (Labroides dimidiatus) are small, colorful fish found in the coral reefs of the tropical Indo-Pacific region. They are known for their unique symbiotic behavior with other marine species, where they act as cleaner fish by removing parasites and dead skin from larger fish.

Cleaner wrasse have a distinct blue and yellow coloration with black stripes running horizontally along their bodies. They have a slender body shape and a small mouth, which allows them to pick off parasites from the bodies of visiting fish.

These fish have a complex social structure, with dominant individuals occupying cleaning stations on the reef where they cater to the cleaning needs of other fish. They are known to perform intricate dance-like movements to attract clients and establish trust with them.

Cleaner wrasse play a crucial role in regulating the health of reef fish populations by removing parasites that can cause diseases. They have even been known to help fish with injuries by cleaning and removing dead tissue from wounds.

Despite their essential role in the ecosystem, cleaner wrasse populations are facing threats from habitat destruction, overfishing, and the aquarium trade. Conservation efforts are being made to protect these fascinating and beneficial fish species.
