It has blue highlights around the eyes and gill covers, mimicking the Lemonpeel Angelfish Centropyge flavissimus. Many of the Acanthurus sp. mimic angelfish. When mature, the body color darkens towards tan with red highlights forming around the eyes and pectoral fins. The dorsal, anal, and caudal fins take on the hues of green but remain tipped with the tan body color.
