Just a few blocks away from my favorite fishy store is the O Street Aquarium. If you are into saltwater fish, they have some neat reef and/or coral tanks to peek at. However, the isles are EXTREMELY cramped, and some of the fish didn't look so good. I did not purchase any fish. I did purchase some goods, and the staff was friendly. They had aquariums, but they were over priced. Interesting to check out, but I wouldn't necessarily go back.
