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.
