About
The Fish Store / Custom Aquariums is a marine-focused aquarium store in Port St. Lucie, FL, run by owner Chris, who has built a devoted saltwater following one tank at a time. Walk in and you'll find a compact, well-stocked shop centered entirely on the reef hobby — saltwater fish, corals, live rock, and invertebrates, plus premixed saltwater and RO/DI water for weekly water changes.
New fish and corals arrive most weeks, so the selection rotates, and regulars stop in several times a week just to see what's new. What keeps people coming back is the livestock you can't find everywhere. Recent visitors have praised the run of exotic, hard-to-find saltwater fish for sale in Port St.
Lucie, FL — one customer finally tracked down a sweetlips he'd hunted for over a month and called it his 'dream fish,' while others come in for colorful damsels and a coral selection that always looks healthy and happy. If you're hunting for corals or reef fish near me along the Treasure Coast, this is the kind of small shop reefers will drive in from Tampa to visit for the selection and the prices alone. Chris is hands-on with everything, from coral recommendations to full custom builds.
He and his team design and install tanks as large as a 180-gallon Waterbox Peninsula 6025, returning afterward to set the rockscape and add water, and they travel across Florida for installs and ongoing service. Beyond livestock, the shelves carry frozen and fresh fish food, testing supplies, lights, pumps, and sumps. Newcomers especially appreciate the patience here — the owner and store manager are known for going above and beyond, and for talking customers out of a fish or coral their tank isn't ready for, prioritizing the animal over a quick sale.
For Port St. Lucie's saltwater community, this remains the go-to spot for coral, reef livestock, and genuine hands-on guidance.

— ANDREW SABOURIN5.03 months ago“Best place in town”
— Esequiel “biigsoonk32” Castaneda5.04 months ago“I walked into this store with no knowledge, just we wanted a saltwater aquarium. The owner Chris helped walk us through everything we would need and ordered it for us. He came and installed our aquarium and got everything setup. We go in multiple times a week to buy saltwater and get supplies/fish. We always walk in with a lot of questions and walk away with so much information. Chris and Paul are extremely knowledgeable, and are always happy to give us feedback and advice. Most importantly they really care about their fish and coral. They won’t sell you anything that your tank isn’t ready for, and they will help you get to where you need to be. Chris goes out of his way to make sure we get everything we want from our aquarium. They also travel around Florida doing installs and service. So lucky to have such an amazing fish store close to me. Highly recommend even if you have to make a drive!”
— Austin Bacarro5.02 weeks ago“Chris and his team recently installed a 180 gallon Waterbox Peninsula 6025 saltwater aquarium in our home. It is a large tank and the guys did an amazing job. Chris returned last week to assist in placing our rockscape and adding the water. We want to thank everyone at The Fish Store!”
