A reef-associated species that occurs at depths of 2 to 60m (5-220ft). It is associated with clear water around coral reefs, rocky bottoms, wreck sites and seagrass beds. Individuals are usually found in pairs or larger schools. Juveniles are generally found in shallow water habitats, including seagrass and occasionally mangroves. Older life stages occur in deeper reef habitats. Density of this species is higher on shallow reefs, but its size was greater on deeper reefs. This species schools during the day and disperses in late afternoon to feed. Common food organisms include bivalve molluscs, crustaceans and small fishes, as well as benthic invertebrates as peanut worms (Sipuncula) and heart urchins (Spatangoida).
Minimum size of maturation for females and males is 30-32 cm and 26-28 cm , respectively. The age of maturation for females is three to four years. This species is a continuous, asynchronous, multibatch spawner, with primary months being April to June. Pelagic eggs and larvae.
