Tired of losing fish to "big box" store advice? At Tropical Lagoon, we combine 40 years of expertise with healthy, quarantined livestock to help you build the aquarium of your dreams.
Many hobbyists struggle because they are sold the wrong equipment or incompatible fish. We change that. Tropical Lagoon Aquarium is Silver Spring's oldest and most trusted aquatic specialist for a reason: we care about your success.
We stock hundreds of species. Whether you are looking for a nano-tank centerpiece or a predator for your 120-gallon, we have it.
From colorful Tetras and Guppies for beginners to rare Cichlids and Discus for the pros. We also carry a massive selection of live aquatic plants to create natural aquascapes.

Struggling with algae or dying fish? Bring us a water sample. We analyze pH, Ammonia, Nitrites, and Nitrates for free and advise on corrections.
Too busy to clean? We offer professional cleaning and maintenance services for homes and businesses in the Silver Spring area.
From nano-cubes to 200+ gallon custom installs, we can help you design the plumbing, lighting, and hardscape.
We take the time to teach you the nitrogen cycle, compatibility, and care requirements. An educated hobbyist is a successful one.
