Key West Aquarium Store

The Underwater Gardener is a locally owned aquarium store located at 2816 North Roosevelt Blvd in Key West, Florida. We specialize in saltwater reef aquariums — coral, fish, complete tank systems, and everything needed to run a healthy marine aquarium — while also carrying a full range of freshwater equipment and supplies.

As an authorized dealer for Red Sea and Waterbox Aquariums, and a stocking retailer for Hydros, Kraken Reef, AlgaGen, Two Little Fishies, and other trusted reef brands, we carry the same equipment and livestock quality you’d find at major online retailers — with the advantage of local, in-person support from people who actually keep reef tanks themselves in Florida Keys conditions.

Whether you’re a longtime Key West local, a new Florida Keys resident setting up your first tank, or a visitor curious about marine life during your trip, we welcome walk-ins. Check our hours and location before stopping by, browse our full online shop, or read our Coral Care Guide for practical, no-nonsense reefkeeping advice.

Visiting Key West? You can still take the coral home.

The showroom is at 2816 North Roosevelt Blvd, on the way in and out of the island. You do not need to own a tank to walk in — the lights are on and the corals are open. If you find one you want, you do not have to carry it onto a plane: pick it in person, and we will pack it and ship it overnight to your door when you are home. Same packing fee and same overnight shipment whether it is one coral or a box of them.
