If it's a juvenile, yes. It will also outgrow your tank eventually, and you'll need a bigger tank or sell it back to the LFS. For example, right now I have a juvi Koran angel, but I know it will eventually get too big for my tank. I am in the process of setting up a 120 (building the stand for it right now), but that will be a reef tank, and the Koran would have fun with that (as in eating all the corals). So it's going to eventually return to my LFS where it will probably end up in their display FOWLR tank and be much happier as an adult.
