There are a bunch of places down here, including Clams Direct. If you wanna stop by and see Barry, though, make sure that you call ahead, he is in and out because it's pretty much a mail order business.
There's also Aquatic Warehouse, VM Aquatics, Pet Kingdom, and Octopuss Garden. You can find all their information on this thread in the local SD reef forum:
