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).
偏愛珊瑚礁與清澈的水域。 在墨西哥灣，它出現於清澈的深礁中。 (至少 45 公尺) 在百慕達群島與西印度群島，此魚種是常見於淺水區，但是它通常躲在洞穴或岩架下中在白天期間。 此魚種對被在 16 公分TL 時成熟而且轉換雄性於大約 20 公分的雌性感到雌性先熟。 雄姓具有領域性。 主要吃小魚與甲殼動物。 可能跟隨海鰻，而且蛇鰻覓食被驚嚇的獵物。 小心的, 但是可接近的.(參考文獻 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. 西大西洋: 美國南卡羅萊那州與百慕達群島到巴西南部。
