Adults prefer coral reefs and clear water. In the Gulf of Mexico, they are found in clear deep reefs (at least 45 m). At Bermuda and the West Indies, they are common in shallow water, but they usually hide in caves or under ledges during the day. The species is protogynous with females maturing at 16 cm TL and transforming to males at about 20 cm. Males are territorial. Feed mainly on small fishes and crustaceans. May follow morays and snake eels to feed on flushed preys. Wary, but approachable (Ref. 9710).
Mature females transform to males at a length of about 20 cm. Spawning occurs just before sunset over several days, and a male will spawn daily with each of the several females in his harem. Fecundity estimates range from about 150,000 to 282,000 eggs per female; with eggs 0.95 mm in diameter and having a single oil globule.
