Inhabits reef flats and lagoon and seaward reefs to a depth of 40 m or more. Occurs singly or in small to large aggregations, taking shelter in dark crevices, branched coral, under ledges, and among the spines of Diadema setosum. Nocturnal species (Ref. 7300). Feeds on small crustaceans and gastropods, also on small fishes. Generally common (Ref. 9710). Has been reared in captivity (Ref. 35404).
