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).
一个具有领域性种用死的鹿角珊瑚普遍发现于珊瑚礁区域。 吃被由这些死珊瑚支撑的菌丝藻。 时常袭击没有暂停的入侵的人类, 有时咬一口令人疼痛那是温和的警告当非预期的时候。 特别具有侵略性在生殖的期间。 在与侵略者遭遇的时候发出一个卡嗒声。 对于大多数的食草鱼与一些其他的鱼表现出侵略性; 为摄取食物的利益防护它的领土。 (参考文献 47011)
