I did a compromise and saw how it did at the LFS for a few weeks, but then I did put it straight into the tank (in an acclimation basket) when I first got it. Slippery little bugger managed to wiggle out of it and got lose in the tank before I was ready. My Melanurus Wrasse WAS NOT AMUSED!!!!!!!!!!! I had my Foxface in another basket as the plan was to add them together, given the aggression that the Melanurus showed to the Blue Star Leopard, I had to add the Foxface as well to help divert attention to another new fish, so in he went. My CB and Melanurus swam up to the Foxface as if to say "Hey, this is our turf" The Foxface simply flexed it's spines and the other two turned tail and went the other way in a hurry.
