The Orangespot Surgeonfish is also known as the Orange Shoulder Tang, Orangeband Surgeonfish, and Orange-epaulette Surgeonfish. Each of these names point to the distinct and interesting feature that makes this species stand out, the bright orange horizontal band with a broad blue edge on its side.
Not only is this fish quickly recognized by its orange spot or band, but it also goes through a fascinating color change as it matures. As a juvenile is solid yellow with just the slightest hint of blue edging the anal and dorsal fins. The adult looks quite different. The front half of a mature specimen is a light gray and the back half is a dark gray-blue, and its caudal fin becomes lyre shaped. In each case it still retains its shoulder marking, but the orange spot does becomes more brilliant with age.
