Ich in the morning only

[Crush Coral]

I picked up a Royal Gramma and added it to my reef tank about a week ago. Now it has 2 - 5 spots of ich on it when I turn on the tank lights but it goes away after a couple hours. Any ideas?

That is the normal ich life cycle. The parasite has a free swimming stage. The spots you see are the fish reacting to the parasite.
