They offer some unique items that are worth getting, and aren't really found anywhere else. Inland Aquatics I have also ordered from Inland twice, and was very happy with their service and products, too. They carry many tank-raised fish, and quite a few corals too. I have ordered from Brian Griffin at least 5 times now. He always does his best to satisfy the customer, and his prices are just about the best on the 'Net.
Reefers comes highly recommended.
