Discoloration in yellow tang

[mvickramm]

Guys......
My yellow tang is not completely yellow. I found a patch on one side of his body. It looks more like rosy whitey kind of thing. More like flesh...but no bleeding nothing... just the color. Its not bright yellow on that part. Can you please tell me what might be the problem? He is acting normal though... eats and roams well......
Thanks,
Vick
