Dottyback and Six Line Wrasse?

[Wrench]

I just got a Six Line from the LFS. From my research and speaking with local reefers, I was under the impression that they could hold their own in a tank with other semi agressive tankmates. My Dottyback, however, is bullying the heck out of my new wrasse. How long should I give them to get along before I get rid of one of them? The dottyback tried bullying some of my Chromis at first but when they fought back he learned his lesson. I am hoping that the Wrasse will do the same. Any thoughts?
