A member of the surgeonfish family that has distinctive coloration and is occasionally encountered by anglers, the blue tang is sometimes used as an aquarium fish and is also marketed fresh.
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.
