SCALES Tropical Fish Warehouse is a state-of-the-art aquarium retail super-store in the Maryland Suburbs of Washington, DC. SCALES is owned and operated by experienced aquarium hobbyists. We designed SCALES to be the store that could serve both freshwater and marine aquarium hobbyists from beginners to experts. We carry the highest quality fish, inverts and plants for the best price consistent with that quality. We only sell products that work and never offer advice to sell you anything you don’t need!

SCALES is clean, comfortable, brightly-lit and has experienced, friendly staff to help you with your aquarium.

The aquatic life support systems at SCALES have a capacity of more than 18,000 gallons of water in more than 600 aquariums. State-of-the art filtration and maintenance systems ensure the health and quality of all of the aquatic animals for sale. Clean tanks are just a beginning to a great aquarium store though. Great selection and knowledgeable staff in a modern atmosphere will make your experience at SCALES different than any aquarium store you've visited. In addition to our retail facility, we offer a wide variety of services associated with aquariums, ponds and other aquatic displays.

Conveniently located about 3 miles West of Route 29 at the corner of Briggs-Chaney Road and New Hampshire Avenue, SCALES is just 15 minutes away from either Columbia Town Center, or downtown Silver Spring.
