Petland has a nice selection but their quality isn't the best
The place I've been going to is Scales and Tails in Easley. The guy who runs the place knows what hes talking about and is very nice and helpful. They'll special order anything they don't have in stock and take great care of their fish. Also have a good selection of live plants.
