Adult: Sloping head with a relatively large mouth, a tapering body and a notched tail. Body with blue horizontal stripes over a yellow-gold background. Tail and rear end of dorsal fin dark with yellow margins (cf Caesar Grunt, H. carbonarium), other fins yellow.
Juvenile: Spot at fin base, body with yellow and dark longitudinal striped.
Drift in small to midsize schools, down to 30 meters. Adults are found in small or large groups over coral and rocky reefs, as well as mangroves and seagrass beds. Large adult members of this species are more abundant on reef/boulder habitat than on seagrass beds. It is found in small groups over coral and rocky reefs and drop-offs. Adults make nocturnal migrations into adjacent seagrass habitat. Adults also exhibit very high site fidelity to diurnal resting sites on the reef, with little movement during diurnal periods.
Adults feed on crustaceans, bivalves and occasionally on small fishes, as well as foraminifera and gastropods. Maximum total length is approximately 46 cm and the maximum published weight is 750 g. Maximum recorded size in seagrass habitat matches the smallest average sized individuals of within mangrove shorelines, which strongly suggests that mangroves are utilized as a secondary or sequential habitat by members of this species
There is evidence that it forms spawning aggregations
