My Yellow Tang is picking on my new Fox Face

[safety4fire]

I purchased a Fox Face yesterday from BA's in Edmonton, I brought it home and of course it went into camouflage mode, as soon as it found a place to hide my Yellow Tang started to harass it, the Fox face is bigger than the tang and just stayed on the bottom of the tank in the corner as the Tang would push its self against it, The yellow tang has two white prongs on it's tail, I am assuming it was trying to poke these at the Fox Face. This morning the Fox Face is still in camouflage mode on the bottom of my tank in a corner.

Do you think I made a bad choice putting him in my tank with my Yellow Tang, or will it just take some time to adjust?
