Hmm. Well I guess since Baltimore and DC aren't too far apart, we can do stores in both areas. Baltimore has got some nice ones.
Exotic Aquatics, House of Tropicals, and Sea Save. Also Aquarium Depot which is a bit outside of Baltimore.
Then if we went the DC route, there is Tropical Fish Warehouse in Gaithersburg, Scales in Cloverly, and Congressional in Rockville.
I'd rather go the Baltimore route. More stores for the freshies that way and I think they are all a little closer together than the DC stores. It'll mean a bit longer drive for you though Mike.
