Drew, Dick, and Johnny,
Thanks for your quick replies

I currently have them separated at each end of the tank. The little guy keeps wondering over near the other one then I have to separate them.
I think what set my large on off was that after putting in the new one in he immediately went to the other end of the tank and dove into my other clowns host coral. I am going to leave the lights off for another two or three hours and see how things go.
I would put him in my hospital tank but I just tore it down two days ago (setting up a prop/fish room) I should have the tanks up and going in about three days and hopefully the little guy makes it.
