A territorial herbivore. Adults inhabit reef flats, shallow lagoons, and semi-sheltered reef margins; common among patches of rubble or porous reef rock, surrounded by live coral, particularly in areas of mild surge (Ref. 1602). Also in high energy zones with mixed corals and short algae. They occur in small loose aggregations (Ref. 48636). Feeds on filamentous algae (Ref. 89972). 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).
居住於礁石平臺，潟湖淺灘與半掩蔽的礁區邊緣的一個具有領域性草食動物; 普遍在碎石區塊或多孔的岩礁之中, 被活珊瑚包圍了, 特別地在溫和湧浪的區域中.(參考文獻 1602) 也在高能量的有混合珊瑚與短的藻類的地方。 出現於小的鬆散魚群。 (參考文獻 48636)
