Territorial, inhabit shallow lagoon and subtidal reef flats. Form large aggregations above staghorn Acropora thickets or in smaller groups above isolated coral heads. Feed on zooplankton, benthic invertebrates, and algae. Males invite females to spawn in their nests; protecting the eggs until they hatch and becoming very aggressive against other fish. Eggs hatch after 3-5 days; pelagic larvae feed on plankton (Ref. 5503). Oviparous, distinct pairing during breeding (Ref. 205). Used in behavioral study. Have been reared in captivity (Ref. 35412). Diurnal species (Ref. 54980, 120737).
領域性, 居住於潟湖淺灘與亞潮間帶的礁石平臺。 上方鹿角 Acropora 叢形成大群的魚群或者在上面孤立的珊瑚頂部形成較小群魚群。 吃浮游動物，底棲的無脊椎動物與藻類。 雄性邀請雌性產卵於他們的巢中; 保護卵直到他們孵化，而且變成對其他的魚非常有侵略性。 卵在 3-5 天之後孵化; 大洋性的仔魚吃浮游生物。 (參考文獻 5503) 被用於行為的研究了。 曾經後面在繁殖場.(參考文獻 35412)

成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Male selects and protects the nest; does the courtship `dance' about 1 m above the nest and escorts the attracted female to the nest site where spawning ensues (Ref. 33146). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Also Ref. 103751.印度-西太平洋: 紅海而且東非到列島群島，馬貴斯群島與 Tuamoto 島; 北至日本南部; 南至澳洲雪梨。
