A territorial species commonly found in coral reef areas with dead staghorn corals. Adults feed on filamentous algae supported by these dead corals. Frequently charge human intruders without hesitation, sometimes taking painful nips which are mildly alarming when unexpected. Particularly aggressive during reproductive periods. They emit a clicking noise during aggressive encounters. Act aggressively toward most herbivorous fishes and some other fishes; defend its territory for feeding advantages (Ref. 47011). 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).
一個具有領域性種用死的鹿角珊瑚普遍發現於珊瑚礁區域。 吃被由這些死珊瑚支撐的菌絲藻。 時常襲擊沒有暫停的入侵的人類, 有時咬一口令人疼痛那是溫和的警告當非預期的時候。 特別具有侵略性在生殖的期間。 在與侵略者遭遇的時候發出一個卡嗒聲。 對於大多數的食草魚與一些其他的魚表現出侵略性; 為攝取食物的利益防護它的領土。 (參考文獻 47011)
