About
Tucked away in Gulfport, Florida, AJ's Aquariums LLC is a coral-focused, by-appointment aquarium store run by Alex — a hobbyist-turned-vendor whose passion is obvious the moment you walk through the door. This isn't a sprawling big-box pet shop; it's an aquacultured coral facility, and reviewers across the Tampa Bay and greater St. Petersburg area consistently call it the best reef selection they've found.
With a five-star rating across 40 reviews, AJ's has earned a devoted following among local saltwater hobbyists. The displays are the draw. You'll find euphyllia torches, hammers, and goniopora for sale in Gulfport, FL, alongside clams, anemones, clownfish, and zoanthids — much of it fully aquacultured, propagated with care rather than wild-harvested.
One reviewer with over 50 years in the aquarium and marine-science industry calls Alex the most knowledgeable person he's met, crediting a background in marine science and water chemistry and a commitment to aquaculture that eases pressure on wild reefs. Frags are repeatedly described as larger and healthier than expected, pest-free, and competitively priced even at the higher end. Because AJ's runs by appointment, every visit comes with Alex's full attention.
Customers describe him walking through the pros and cons of specific specimens, talking through tank compatibility, and helping first-timers get a saltwater tank started — never pushing a sale, always educating. He also quarantines his fish before they're available, giving reef keepers genuine peace of mind about livestock health. For coral and reef hobbyists anywhere in the Gulfport and St.
Petersburg area, AJ's Aquariums delivers one of the most focused, highest-quality saltwater shopping experiences in Florida — healthy livestock, generous sizing, and knowledgeable, no-pressure guidance every visit.

“I’ve been in the aquarium and marine science industry for over 50 years and can tell you Alex at AJ Aquariums is the most knowledgeable person I’ve ever met. He has a scientific background in marine science and water chemistry and a passion for not just the hobby but aquaculture which reducers the pressure on the marine ecosystems. Would highly recommend”
