Adults brownish gray with a yellowish cast; vertical dark lines following scale rows; a large blackish spot covering most of pectoral base, darkest near upper part; pectorals slightly dusky.

Adults inhabit inshore and offshore coral reefs. They are found within caves at night (Ref. 9626). Often found in tangles of staghorn coral; anywhere there is abundant algae on reefs (Ref. 26938). Feed mainly on algae but also on harpacticoid copepods, small gastropods, eggs of mollusks, sponges, polychaetes and hydroids (Ref. 9626). Juveniles subsist on the external parasites of fishes (Ref. 5521). Adults pugnaciously guard large territories, will chase and nip intruders of all sizes, including divers (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Taken incidentally in traps and small-meshed beach nets (Ref. 5217).
棲息於岸邊與外海的珊瑚礁。 在洞穴裡面發現在晚上。 (參考文獻 9626)時常發現於鹿角珊瑚的纏結; 在任何地方在礁上有豐富的藻類。 (參考文獻 26938) 主要吃藻類也捕食哲水蚤，小的腹足動物，軟體動物，海綿，多毛類動物與水息蟲的卵.(參考文獻 9626) 稚魚捕食魚的外部寄生蟲。 (參考文獻 5521) 好鬥地保衛大的領土, 將獵逐而且捏所有大小的侵入者, 包括潛水者.(參考文獻 9710) 在魚籠與小網目的海灘網中附帶地捕獲了。 (參考文獻 5217)
