Is this Ich or something else?

I have a Power Brown Tang that has fuzzy white spots on its fins. Today is the first day that I have seen them. They are no where else on the fish. I wanted to know if it is Ich or something else. Thanks

Looks like lymphocystis to me.

If it's lymp, it will go away on it's own and its not catchy.
