Comments: Adults occur in lagoon reefs and generally prefers small patch reefs with sand or rubble substrates (Ref. 1602).  Feed on benthic algae which it aggressively guards against other herbivores (Ref. 9710).  Juveniles secretive in rubble (Ref. 48636).  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). Diurnal species (Ref. 113699).
