Μέγεθος / Βάρος / Age
Maturity: Lm ? range ? - ? cm
Max length : 16.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 9710)
Ραχιαίες άκανθες (συνολικά): 13; Μαλακές ραχιαίες ακτίνες (συνολικά): 13-15; Εδρικές άκανθες 2; Μαλακές εδρικές ακτίνες: 13 - 14. Adults have a large black patch on the abdomen reaching the anus; juveniles an ocellus over the center of the dorsal fin base (Ref. 48636). Body white, anterodorsal (or sometimes entire half of body) dark brown, opercle spots prominent pale large, belly patch dark brown. Body depth 2.0-2.1 in SL (Ref. 90102).
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).
