These blue tang fish can reach a maximum Size of 10 and 12 inches (30 cm), and their oval-shaped bodies, which have been compressed laterally, enable them to swim quickly and nimbly through the water.

The blue tang has an acute, extendable spine near the base of their tail that they can use for protection, just like other surgeonfish species.
