Adults live in empty tube-worm snail shells, often extending the head from the opening. They feed by joining loose groups of look-alike rainbow wrasse and darting out to nip at nearby fish, taking mucus and perhaps small bits of flesh (Ref. 5227). The skin of larger fishes is the mainstay of the diet, although they are also known to eat eggs (Ref. 28023). Oviparous (Ref. 205). Eggs are attached to the walls of the parent's shelter and are brooded by the male parent (Ref. 56053). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Oviparous, distinct pairing (Ref. 205). Males guard the eggs until they hatch (Ref. 56053).
