I've heard of local aquarium clubs in several cities, but none in Charleston SC. I'm sure it's a good sign that there isn't one when Google can't turn up anything, but that isn't automatically true. Anybody know where else I might check?
Check your lfs. Not PetsMart or any other national chains. Your local mom and pop store. Most clubs will put up a flyer in the store. Or just simply ask the owner. If there is one in the area, they will know about it.
