Good picture. Yeah, he will be fine. It is normal for fish to get a little spotty after being introduced into a tank. Once they are acclimated fully the spots diminish. When the fish gets stress the spots come back. Essentially, the parasites are always there, they just manifest visually during a certain cycle of their life.
It has been my experience that the best method for keeping a fish healthy is to make sure that the diet is giving them all that is needed. If they are getting all that they need then their immune systems can keep the ich at bay, just like in the wild.
