Spot on blue hippo tang

[junglejim1022]

I have a large blue Hippo tang that I have had for about three years and never had a problem with her and now I see a spot about the size of the end of a pencil eraser, it is white in color. Anybody got any idea what it is and what I can do to get rid of it. I sure would hate to lose her.Thanks

Where is the spot located? fin/body? Is it raised, flat, any texture to it?
Any way to post a pic?

The spot us located just behind her front fin on her side. It is flat, no texture. I will try to post a picture tomorrow. Thanks
