Trophic Strategy
provided by Fishbase
Found in rocky shore areas and rocky surge channels with little coral growth at less than a meter to 6 m deep (Ref. 90102). Occurs on large encrusted boulders, vertical rock walls, and large shallow caves; surge channel at edge of rock platform, spotty corral, and sand and encrusted rock bottom (Ref. 9849).

Biology
provided by Fishbase
Adults are found in rocky shore areas and rocky surge channels with sparse coral growth at depths of less than a meter to 6 m (Ref. 9849). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
