Juveniles are common in tide pools while adults are found over shallow reef tops. Adults frequently form large feeding aggregations of up to several hundred individuals. Food items include algae, small crustaceans and fish, and various invertebrate larvae (Ref. 3139). At Fernando de Noronha Archipelago, this species feeds on spinner dolphins’ feces and vomits. The offal feeding may be regarded as a simple behavioral shift from plankton feeding to drifting offal picking. Also, juveniles may hold cleaning stations together with the doctorfish (Acanthurus chirurgus) and the blue tang (Acanthurus coeruleus) and graze algae as well as pick molted skin and parasites from green turtles (Chelonia mydas ). This behavior is preceded by a characteristic inspection usually followed by feeding nips on the turtles’ skin (head, limbs, and tail), as well as on the carapace. The most inspected and cleaned body parts are the flippers (Ref. 48727, 51385). Adult males adopt a bluish ground color when guarding eggs. Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Attracted to divers who feed fish. Marketed fresh (Ref. 3139). Has been reared in captivity (Ref. 35420).
稚魚常見於潮池雖然成魚發現在水淺的礁頂上面。 成魚時常形成向上到幾百個個體的大覓食群集。 食物組成包括藻類，小型甲殼動物與魚 , 與各種不同的無脊椎的仔魚。 (參考文獻 3139) 在 Fernando de Noronha 列島，這種吃飛旋海豚的殘渣與吐出物。 碎肉進食可能是從浮游生物進食到漂流碎肉採集視為單一的行為變化。 同時, ，稚魚可能支撐 , 清潔的區域伴隨著魚醫生 ( 小帶刺尾魚〔Acanthurus chirurgus〕 ) 與藍色的強烈味道 ( 藍刺尾魚〔Acanthurus coeruleus〕 ) 而且啃食藻類以及剔啄脫皮來自綠海龜 ( Chelonia mydas) 的皮膚與寄生蟲. 這行為進行通常被跟隨著的一個特殊的檢查咬食海龜的皮膚 (頭部，肢翼與尾部), 以及甲殼。 最檢查而且清理身體部份是鰭狀肢.(參考文獻 48727,51385) 雄性成魚擁有一個藍色的底色何時守衛魚卵。 卵生的, 在繁殖的時候明顯的成對。 (參考文獻 205) 卵是底棲的而且附著到底部。 (參考文獻 205) 被吃魚的潛水者吸引.。 在市場上銷售生鮮地.。 (參考文獻 3139) 曾經後面在繁殖場.(參考文獻 35420)
