I would say you need to put a equal size Sohal in there if you want him to have a chance. Or be prepare to take him out. THis is what i did when i added another tang to my tank a awhile back

I bought a yellow tang and put him in a bag to let the other fish see him. once he was there I got a rubber maid container to use the clear ones so eveyone could see him even the scopas. Then I would feed the fish nori and hang it by the clear container and then the other tang would have to come up by the container to get the nori and he would see the tang. freak out after awhile the scopas just didnt care. It worked for me
