📖 Overview

Adults inhabit clear, coral-rich areas of lagoon and seaward reefs . They hide in deserted worm tubes or other small holes when alarmed , bite divers occassionally . They feed on the skin, mucus and sometimes scales of other fishes by quick attacks. Oviparous. Eggs are demersal and adhesive , and are attached to the substrate via a filamentous, adhesive pad or pedestal . Larvae are planktonic, often found in shallow, coastal waters . Juveniles mimic the cleaner wrasse Labroides dimidiatus . According to Ref. 53299 they are facultative mimics that change their color: at cleaning stations they mimic the cleaner wrasse and attack unsuspecting customers; elsewhere they adopt an alternative color and striping pattern to conceal themselves among fish shoals from which they can strike at passing fish.
