Overview
Comprehensive Description
Biology
Adults are found around dead coral outcrops, also in rubble areas in lagoons and on the outer edge of reefs (Ref. 510). 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).
