Adults inhabit coral and rocky reefs, juveniles often commensal with large sea anemones, sea urchins, or small coral heads (Ref. 4391, 48636). They occur in small to large aggregations. Stomach contents include algae, copepods, and other planktonic crustaceans (Ref. 7247). 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). Diurnal species (Ref. 54980; 120737). Minimum depth reported taken from Ref. 128797.
棲息於珊瑚礁與岩礁, 稚魚時常與大的海葵，海膽或小的珊瑚頂部共生。 (參考文獻 4391,48636) 形成小群到大群魚群。 胃內含物包括藻類，橈腳類的動物與其他的浮游性甲殼動物。
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
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). Courtship characterized by male 'signal-jumping'. Captive pair reported to spawn thrice monthly with a total of 17 over a 7-month period (Ref. 2856). While protogyny was originally proposed for this species, recent studies confirmed gonochorism in the form of non-functional hermaphroditism (Ref. 103751).印度-太平洋: 紅海而且東非到列島群島與皮特凱恩群島, 北至日本南部, 南至澳洲雪梨。 不出現在夏威夷與馬貴斯群島。
