Silver Spring? Not sure what you're talking about.
FIns n feather is easy without the toll road. 15S to 7E, exit right on the Belmont exit (Claiborne Parkway), he's a few miles down the road. I live less than 10 min from there.
The 2 mandarins were in his frag tank. Looked great. Good coral and frag selection, like Roka said, but it is a very small store. His SW fish in the other tanks weren't looking so hot last week though.
