Congressional Aquarium

Congressional Aquarium has built a presence in Rockville, Maryland as a shop covering both freshwater fish and reptile sales, drawing customers from across Montgomery County. With 127 reviews and a 3.4 rating, it's a familiar name for hobbyists in one of Maryland's most densely populated and diverse counties. Rockville sits at the heart of a large suburban market, with nearby communities like Gaithersburg, Bethesda, and Silver Spring all within a reasonable drive. The shop's dual focus on fish stores and reptile retail gives it broad appeal for pet keepers of different interests.

Congressional Aquarium operates as both a local fish store and a reptile shop, stocking live animals alongside the equipment and food needed to keep them. On the reptile side, expect to find a rotating selection of commonly kept species along with substrates, UVB lighting, hides, and feeding supplies. The fish store side brings in freshwater and potentially saltwater species, plus tanks, filters, and water treatment products. Staff familiar with both departments can often give practical care advice across both hobbies, which is handy for customers who keep mixed setups.

Congressional Aquarium serves Rockville and the broader Montgomery County area, including Gaithersburg, Germantown, and Bethesda. Its location makes it accessible to customers coming down from Frederick County or up from Chevy Chase and Silver Spring. The shop also draws visitors from just across the DC border who prefer a local store to big-box pet chains.
