Well if you want to drive to Columbia, Fishy Business is by far my favorite. But I'm currently in Greenwood and have just started working with a local place here called Eric's Tropical Pets. The Dwarf Blue Gourami I got from her is awesome and she can order in just about anything you need (just got two Black Lyretail Mollies - exactly what I wanted the to look like too). She doesn't have any quarantine tanks in back so when she gets her shipments in, she has to put them into the sale tanks and from what I've noticed, so long as you either get the fish when they first come in (like I did with these Mollies, still in shipping water) or wait a 3-4 days after the shipment comes in, everything is good.
