You could swap the Domino into the sump for a while to get your wrasse acclimated, but the Dominos can be a problem with each new introduction. I don't have enough information on what else, if anything, you would like to stock the aquarium with along with what's in there right now... so i'll take the position of permanent removal since these are amongst the most aggressive and territorial of the damsels (which is already a tough group) and I am assuming that the Yellows are along the same lines as the regular dominos.
I think it's worth a try off the bat to just try and net it out. Using flake food, you can get the damsel up to the surface. Just use the largest net you can get away with and be quick (i've used this to get two yellow tail damsels out of a 125 reef in a lfs before. After that, depending on how you have structured your rock work, try to divide it with egg crate and remove the side needed into some buckets until he is able to be netted. It sounds like a lot of work but really only takes minutes. If yours has an affinity for going into holes or caves, you could try putting in a conch or whelk shell. When he inspects it, quickly remove (i did this to get a flame angel out of that same 125gal reef).
I like to net feed my fish. I thaw frozen food, strain it into a net and then dip the net into the tank. The fish loose their fear of the net and become easy to remove in the future. Takes a while, but they come around.
Hope this helps and good luck to you.
