The oval, profound-bodied, and packed blue tang is more roundabout than are different surgeonfish. Its coloring is almost entirely blue, ranging from powdery to deep purple, and it has many dark or light blue horizontal stripes running down the sides and blending into the background.
The dorsal and the anal fins have a bright blue border, and there is a white or yellow spine on the base of the tail. Juvenile blue tang are colored bright yellow, while middle of the road fish have blue heads and bodies and yellow tails.
