Common on reefs at any depth where it maintains cleaning stations near large coral heads or ledges.  Attracts customers by darting about in an erratic manner.  Fish of all kinds are known to visit cleaning stations frequently, where they may be observed waiting for their turn, hovering motionless with fins extended, mouth and gill cover open, as the wrasse removes parasites and dead tissue.  Research has demonstrated that fish from reefs where cleaners have been removed become more susceptible to illness.  Juveniles are black with purplish-blue above.  Attains 4 inches.  Endemic to Hawai'i.  Related to Labroides dimidiatus of the Indo-Pacific.
