Yeah, that is normally okay. However, if any of the other fish at the LFS have ich, I would hypo the new fish, even if you don't see any signs on him yet. He might be carrying ich, and you may never know. If you don't decide to hypo the fish, when you introduce that fish into your tank however, one of your fish in the tank with a lower immune system will contract the ich that your new fish was carrying.
