Dorsal spines (total): 7; Dorsal soft rays (total): 27 - 29; Anal spines: 1; Anal soft rays: 25 - 28; Vertebrae: 26. Yellowish to greenish gray in color; lower half of eye to ventral of chin nearly enclosed by a broad blue-edged dark red to purple area; opercle with 2 diagonal bright blue bands; pectoral fin base with an orange-red bar broadly bordered with bright blue.

This schooling species inhabits exposed seaward reefs in relatively shallow water, over hard bottoms. Usually many individuals occupy the same refuge. Found to be subjected to strong currents, where in small to large aggregations (Ref. 48637). Feeds on zooplanktons (Ref. 89972).
