I have one, but for some reason it never shows any of it's colors like tang mans. It is always a dull shade of grey with very little color on the fins or face and the black saddle is always washed out. Nothing bothers it, water parameters are good and it eats well. Maybe there is something I am missing in it's requirements? I've seen them at the LFS in less than ideal conditions and they always look great. It is a nervous fish - darts behind the rocks when anyone approaches. They are supposed to be good algae eaters, but mine only takes an occasional nibble at the rock.
