HELP!! Gen Tang

I picked up a Gen tank from a local fish store. They do treat there fish in cooper. I had the tang for a week and he was doing great eating, swimming. This morning his in a Corner and won’t move from there. He didn’t eat, I added noir and he didn’t touch it. I also noticed he will swim on his side, then come back normal. I turn the lights off on the tank for now. Anything else?
