Biology:  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).
