Tucked away in Madison, Tennessee, 7 Seas Aquatics LLC has quickly become one of the Nashville area's most talked-about fish stores, earning a reputation for what multiple reviewers call the best coral selection in the city. Owner James and his team — including his son Ben, along with staff members Josh and Adam — have built a shop where coral fragging happens on the spot from display tanks, custom tank modifications are part of the service, and honest advice often means talking a customer out of a more expensive fish in favor of one that'll actually thrive. The saltwater side is clearly the star here.
Reviewers rave about the torches, hammers, and diverse coral frags available, alongside saltwater fish like flame angels and powder brown tangs. One customer noted the store goes toe-to-toe with the best reef shops in Nashville. But 7 Seas is no one-trick operation — the freshwater section earns its own praise for unique species, including discus, bettas, and live plants.
Mystery snails and pond-appropriate stock round out the livestock offering. What stands out in nearly every review is the level of genuine care. Staff will walk customers through water testing, troubleshoot system issues, and share years of hands-on experience with lighting and water parameters.
James in particular is praised for prioritizing long-term customer success over short-term sales. The shop also offers trade-ins for store credit, and occasionally stocks used full tank setups — a real bonus for hobbyists on a budget. The tanks throughout the store are consistently described as clean, with healthy livestock across the board.
The space itself is roomy and well-organized, making browsing a pleasure rather than a chore. Several reviewers specifically mention switching from big-box pet stores and never looking back. For anyone in the greater Nashville area serious about saltwater reef keeping or looking to stock a quality freshwater setup, 7 Seas Aquatics delivers substance over flash.

This was my first time going, but my son had been here several times previously. I was impressed by the clean tanks, and they had a good selection of fresh and salt water fish. The people working were extremely nice and helpful.

Really cool shop with lots of fish on display, plenty of coral options, and they were super friendly and helped me figure out which plants and fish I needed to add to my pond.

7 seas is an amazing store for anyone just getting into the hobby, and seasoned aquarist alike. There’s a large variety of fish to choose from and all are within a good price range in comparison to other places. The staff are all friendly and willing to work with you, answer any questions you have, and share personal opinions or suggestions based on the info you give them! The owner Mr. James and his son Mr. Ben are both cool as a fan extremely knowledgeable and willing to help hands on with customers and questions. They even occasionally have used full tank setups for sale. My experience with them was nothing short of awesome thank you guys.

This store is absolutely wonderful. James is a nice guy and he knows his stuff. He’s not concerned with a sell but rather a happy customer that would stay in the hobby. He doesn’t mind taking either about fish or just life in general. Overall 10/10

The staff are so knowledgeable and patiently answered all my newbie-fish-owner questions. They are very accommodating and actually talked me out of buying more expensive fish, in order to get some that would be compatible and thrive better in our small tank. Highly recommend 7 Seas! Don’t waste your time at the big box store where they are just trying to sell inventory and don’t care how long your fish live.
