Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This demersal, reef-associated species lives in empty tube-worm snail shells, often extending the head from the opening. It feeds 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 (Humann and Deloach, 1993). The skin of larger fishes is the mainstay of the diet, although they are also known to eat eggs (Grove and Lavenberg, 1997).
