Companions Pet shop has a monoploy on the market since their nearest competition is probably the Petco up in Cleveland Park. As you can guess, they're in a smaller space so it's pretty crowded, but it's a good place to pick up "apartment" pets -- by which I mean birds, fish, and hamsters. The fish selection is probably the most noteworthy since the largest amount of space in the store is devoted to that section. The prices seem reasonable, but then again I couldn't tell you the going market rate for a guppy.
