পৃষ্ঠীয় কাঁটা (মোট ) : 13; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 12 - 14; পায়ূ কাঁটা : 2; পায়ূর নরম পাখনা্তুন্ড: 13 - 14. Bluish or purplish spots at the posterior base of the dorsal fin. Juveniles with large ocellus that reduces with size and lacks completely in adults. The white band in young reduces to a small white saddle in large adults (Ref. 48636). Body depth 2.2-2.5 in SL (Ref. 90102).
Adults occur in protected inner reef flats and shallow lagoons and channels, over rubble and rocky outcrops. Feed primarily on filamentous algae (Ref. 7247). 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. 54980; 113699).
