White patches on fish. How do I treat fish in a SPS tank?

[mmotown]

Came home this evening and looked at my Naso tang and one side of him have white blotches on him . Only one side. He was fine today and tonight he looks a mess. What the hell happened to him? I have had some anthia to die unexpectedly and I am sure the tang contracted something. How can I treat? I have no quarantine tank...:eek1:


?

naso tank does show blotches under stress or at night, but if it becomes consistent, it must be something wrong (sick, water quality...), do you have a pic?

I don't have a pic but last night I did a search and I see that this is common with Naso Tangs. Today it is clearing up. I will see what the progress is in the next day or 2. My tank is stablle and water quality is good.
