Its striking blue and white horizontal stripes have made it for many the 'poster fish' for the Red Sea reef and Persian Gulf environment. Like other tangs, the sohal tang is compressed laterally, making it extremely maneuverable and fast along the reef. It has a horizontal, blade-like spine along the base of its tail on both sides, which folds into the fish, pointing anteriorly towards the head.
