You run led's right?

Did the tank that he came out of have led's on it? If not, I can almost guarantee you that's the problem. If he's not accustomed to them, you will need to turn them WAY down and very slowly acclimate him.

I would also evict the yellow tang. I can bring my fish trap to the swap for you to borrow, as long as you promise to ship it back to me once you are done with it. It's never taken me more than 20 minutes to catch any fish with it.

Is there any chance your clowns are trying to host the lobo? I've seen them kill a coral by continually harassing it.
