Tropical Lagoon Aquarium

Beautiful store! The fish look fat and healthy and there's a good variety. Tons of wood and stones, coral and anenonies. The staff was great. Definitely recommend.

I've been frequenting this store for at least a decade now. I'd have to say hands down one of the best fresh and saltwater aquarium stores in Maryland. I'll venture out to eastern Maryland and metro Virginia in search of special acquisitions. Tropical Lagoon somehow always has the right selection and best prices. Its probably the owner's close attention to detail and his experience coming through. Best DC Metro/MD aquarium store imho.

It’s a good store and a good source for fish and fresh-killed mice. It’s definitely dark and dingy, but they are very knowledgeable. My big gripe is that their phone is always busy (in 2025!!!) so it’s impossible to call ahead to confirm their stock when you want to buy a particular fish.

TLDR: 4 star rating because I am a regular here. However, overall scores are pretty much 3 stars across the board. They have decent variety, the fish are comparably healthy to other aquariums I have purchased from, and the price is also comparable yet unremarkable. I mostly come to this particular aquarium because they regularly stock the stuff that I like to replenish occasionally. The prices here are about the same as other prominent aquariums in the general area. The selection is sufficient, but they have a split selection between fresh water and salt water so you may not quite see the fresh water variety you expect from other places. Customer service is very casual and largely just ok.

Love this store and the owners wayyy overdue for a visit if your in the hobby and been here you know its like a kid in a candy store
