Common in reef flats and shallow lagoons, but hiding by day within Acropora thickets and other corals, as well as in holes and crevices and emerging at night to forage on free-swimming invertebrates (Ref. 1602). Also found in sheltered seaward slopes in 1-20 m (Ref 90102). Feeds on small fishes and benthic invertebrates (e.g. shrimps - alpheids and penaieds; isopods, copepods, crab larvae, polychaete worms); relatively close to cover, within about 1-2 m (Ref. 11890).
