Habitat and Ecology:

Coral reefs, lagoon areas and subtidal reef flats (depth 0-50m). Juveniles secretive often in rubble patches, adults swim openly but are usually shy.  Feeds on a variety of benthic organisms including fishes, sea urchins, crustaceans, polychaetes, gastropods, corals and algae. Territorial and haremic with male territories overlapping two or three female territories. Pair-spawning occurs around sunrise and females care for the demersal eggs until hatching. Sleeps on its side; makes a whirring noise when alarmed.


Fishery Status:

This species is not protected or subject to fishery regulations. It may be caught in the artisanal fishery but if so it is an exceedingly rare component of the catch.
