Since 1965, Congressional Aquarium, Inc., has carried a wide range of both fresh and saltwater fishes. 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.
