Feeding and Diet

The Common Cleanerfish is well known for its feeding behaviour. It establishes a "cleaning station" often a cave or overhang, where it swims in a bobbing, dance-like motion. Larger fishes come to the cleaning station to have ectoparasites removed. The Common Cleanerfish swims around the fish picking off and eating the parasites. It often enters the mouth and gill chamber of large fishes.
