Leopard Wrasse Getting Butt Kicked

[Madreefer]

I'm kind of worried about a black leopard wrasse I just put in my tank. I did my research before I bought it and my sixline, yellow tang and lawnmower blenny are kicking his butt really bad. Could this just be a pecking order and be over soon or will they kill him? I wont be able to get him out of the tank with out removing all of my rock and I'm not about to do that either. The sixline has actually took chunks out of him. I hope they all calm down. I have never had quarrels like this before.
