Sailfin tang

Question idk if my tang is sick or if its just the way it looks, he has these white dots that get really bright when hes showing his stripes but when hes calm there not noticable. He eats like a banshee and is always full of life and not scared at all. Is this just the way the fish looks or not. There only around his eyes but not on his eyes and its identical on both sides in the exact same area unlike ich were theres no uniformity to it, hes fat as heck and eats anythign I put in my tank.

My Sailfin goes from brown to white in a flash. They change there colour a lot. I'd say it's normal. But to be sure how about posting a picture of him

Mine does the same thing. They seem to more on his head, but color for light to dark.
