Since 1965, Congressional Aquarium, Inc. carries a huge selection of rare freshwater and saltwater fish, aquatic plants, and aquarium supplies in Rockville, MD. We carry a broad selection of both common and hard-to-find freshwater fishes in "the cleanest tanks in town." We have more than 25 varieties of live-bearers on hand at any time, from Fancy Guppies to Snow-White Mickey Mouse Moons. Harder-to-find species, like Zebra Plecos, rare Electric Blue Jack Dempseys, Keyhole Cichlids, and Gardneri Killies, fill in the remainder of our tanks. In the 400-gallon saltwater section, everything from Green Chromis to Zebra Stripe Moray Eels can be found. The store has at least one shark egg on hand most of the time. Invertebrate enthusiasts will find everything from camel shrimp to octopuses. In either of our two mini-reef aquariums, one might find anything from acropora corals to elegans corals.
Whether you're new to the hobby, or an advanced aquarist looking to setup a beautiful reef ecosystem, we are the shop for you.

Knowledgeable staff by Michelle H via Insider Pages on 2/10/2008
I have found the staff to be very helpful and always do free water testing. They have taken the time to explain everything to me, and always answer all my questions. The fish are amazing, and the tanks are very clean. Whether you are a…
A++ by Exhumed R. via Judy's Book on 5/8/2007
I went to Petco to look for a Plecostomus Fish (sucker fish) and after scouring the store for an associate for about 20 minutes, I learned that they did not have a single one. The careless worker says to me, "We might have some Wednesday."…
