Coris and Six Line Wrasse

I had a Coris wrasse that decided to evolve into a land creature a while back and got along pretty good with the six line, now I'm looking into getting another Coris, been waiting for one to show up at my LFS; finally yesterday I saw couple of them at OTA, just wondering and asking your experiences having these wrasses together and considering the Coris is larger than the 6L could I be starting a little feud?

Thx
