Épines dorsales (Total) : 12; Rayons mous dorsaux (Total) : 15 - 16; Épines anales: 2; Rayons mous anaux: 13 - 14.
Adults inhabit rocky reefs, below the surf zone (Ref. 9334). Feed mainly on low-profile, attached algae (Ref. 28023). Defend both feeding and reproductive territories by driving off other fishes and divers who come too close (Ref. 28023). 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).
