The Striped Cleaner Wrasse is blue to yellow above fading to white or yellow below. There is a black stripe from the eye to the caudal fin margin. The stripe widens posteriorly.
It has thick lips and a pair of canines at the front of both jaws.
The Striped Cleaner Wrasse 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 Striped Cleaner Wrasse swims around the fish picking off and eating the parasites. It often enters the mouth and gill chamber of large fishes.
