Oh, no bother at all! Yes - if the wrasse seems stable, that would be what I would do. Quarantined Fish is a good source for two reasons; first is the treatments they provide will reduce the incidence of disease. Second, the time this takes weeds out some fish that are "poor do-ers", fish that aren't going to thrive no matter how they are handled. That said, shipping fish causes stress, and that can cause latent diseases to "break", so I always re-quarantine fish, no matter the source.
Here is a story: I had a group of red devil cichlids, they had been in my tanks for years, even reproducing. Only lost one or two here and there. I sent 100 of them to another public aquarium who put them directly on exhibit. A month later I got an irate call from their curator - "why didn't you tell me they had gill flukes!". He was losing fish in droves, but mine were all still just fine! I figured they got sick from something in his tanks, but sure enough, I did a necropsy on one of ours and found a latent gill fluke infestation! If he had dosed them with prazi before putting them on exhibit, he wouldn't have had that problem.
