Look for the door with painted fish around it, descend the stairs, and you'll enter a cramped but densely packed world of freshwater and saltwater fish that has kept loyal customers coming back for over a decade. The space is small, dimly lit, and unapologetically no-frills — reviewers describe it as dark and dingy — but the tanks themselves are shockingly clean and the fish are healthy. That contrast says everything about where the store's priorities lie. The owner's close attention to detail and deep experience show in the quality of livestock and a curated selection that somehow always hits the mark. Multiple customers note finding saltwater species here that don't show up at other local fish stores, and the coral selection is solid enough to satisfy reef hobbyists making a dedicated trip. Pricing is competitive, often beating other shops in the DC Metro and Maryland area. One longtime customer who regularly ventures out to eastern Maryland and northern Virginia for special acquisitions says Tropical Lagoon consistently offers the best combination of selection and value. Staff are knowledgeable and attentive — even when the store is packed with customers, they make time to educate newcomers on water changes and tank care practices. The store stocks both freshwater and saltwater fish along with corals, and at least one reviewer mentions it as a source for fresh-killed feeder mice, hinting at a broader inventory for reptile keepers as well. One quirk: the phone line is perpetually busy, so plan to visit in person rather than calling ahead to check stock. Parking is available in the adjacent lot — free on weekends, metered during the week. For anyone in the Silver Spring or greater DC Metro area looking for a deeply stocked, competitively priced fish store run by people who genuinely care about their livestock, the trip downstairs is well worth it. ## Specializations - **Water Types**: Freshwater, Saltwater - **Livestock & Products**: Corals, Goldfish, Rare Species - **Services**: Consultation - **Known For**: Premium Equipment, Great Selection ## Highlights - Basement location with an enormous selection packed into a compact space - Shockingly clean tanks with healthy freshwater and saltwater fish - Competitive pricing consistently noted as among the best in the DC Metro area - Saltwater species and corals not commonly found at other local stores - Knowledgeable staff who take time to educate customers on fish care ## Customer Reviews **"Tim Dawson"** - 4/5 - 6 days ago > If you can find it, you will be pleasantly surprised. Look for the door with painted fish around it, squeezed between other random shops. Store is in the basement....be ready for stairs. The trip is worth it! Small, cramped space but a great selection of fresh and saltwater fish! **"Jamel Williams"** - 5/5 - a week ago > Very knowledgeable...great staff!!! **"Kevin Rubio"** - 5/5 - a month ago > Great store, Low prices and a lot of fish I visit weekly **"Joaquin Perez"** - 5/5 - 2 months ago > Really hidden gem in silver spring, and was like visiting an aquarium for free! So many different species and the thanks were shockingly clean, I don’t know how they do it! I only have goldfish so I don’t know if they’ll have more for me to come back and buy but I would recommend to place 100%! Lots of saltwater variety. If I ever get a saltwater tank, I know where to go. **"Dustin Shi"** - 5/5 - 3 months ago > epic place with epic staff and epic fish. **"DJ City"** - 4/5 - 3 months ago > Good shop. They had what I needed. Decent coral selection! **"Anh-Tai Nguyen"** - 5/5 - 4 months ago > This is my go-to local fish store. Species shown below are healthy from the store and living in my aquarium . Great staffs and service at Tropical Largoon! **"Andrea Kuoni"** - 5/5 - 5 months ago > This is a location with a pretty good selection of the most popular salt water fish that’s available on the market currently. They had some fish you don’t see a lot in other local stores so it was overall a good visit. The employees were helpful, despite there being a lot of customers they made sure everyone was checked on. I heard them educating someone as well on water changes and best care practices for evolving tanks. I’d recommend this place for sure. Parking is in a lot next to the building, free on Sat/Sun and paid M-F. It is next to a lounge but just take the stairs down. **"Dani Phantom"** - 5/5 - 5 months ago > great care for the fish! **"Christie Sweet"** - 5/5 - 6 months ago > Great variety, friendly staff ## Nearby Stores - [Appalachian Reptiles & Aquatics](https://www.fishstores.org/maryland/hagerstown/appalachian-reptiles-and-aquatics) - Hagerstown, MD - 4.9/5 - [FantaSEA Aquariums | Aquarium Design, Installation, and Service](https://www.fishstores.org/maryland/crofton/fantasea-aquariums-aquarium-design-installation-and-service) - Crofton, MD - 4.8/5 - [Pacific East Aquaculture](https://www.fishstores.org/maryland/mardela-springs/pacific-east-aquaculture) - Mardela Springs, MD - 4.8/5 - [Londontowne Tropicals](https://www.fishstores.org/maryland/edgewater/londontowne-tropicals) - Edgewater, MD - 4.7/5 - [Father Fish Aquarium](https://www.fishstores.org/maryland/salisbury/father-fish-aquarium) - Salisbury, MD - 4.6/5 - [Tom’s Tropicals](https://www.fishstores.org/maryland/nottingham/toms-tropicals) - Nottingham, MD - 4.6/5 --- *Source: [FishStores.org](https://www.fishstores.org/maryland/silver-spring/tropical-lagoon-aquarium)* *Last updated: February 7, 2026*
