Help!! Ich!!

[Lofus]

I woke up this morning to find my A. nigricans (aka white cheek tang, aka powder brown tang) covered in spots. The lights had not fully come on so they looked like little brown dots but now that the lights are on the show up white. there are also a few on his fins.

The tank is 72 bow with LR and a few corals.

Also, in the tank are two percula clowns, four green chromis, and a bicolour blenny. none of them appear to have any of the spots.

Any suggestions on what my course of action should be? I'm currently setting up a hospital tank (30 gal). Should I try to treat him in the main tank? This is my first ich episode so its all new.
