It has been 7 weeks (today, since getting marine velvet) that my tanks have sat fish free. Most sites say 6-8 weeks and it should be fine to add fish again. I was planing on waiting until next week but my checkerboard wrasse might not last that long

Basically (I think it's him or it's my king angel) my lunare wrasse (who I think already killed my red corris wrasse) has been majorly beating up my checkerboard wrasse. His tail fin is looking like a nub that he can barely move, both side fins are badly nipped up to the point where he's not really using one of them. While ideally I'd like to wait the 8 weeks, I'm really worried that my checkerboard wont make it.
So what would you do? Separate the fish back into the displays a week early? or wait it out one more week and hope the checkerboard makes it?
