About
Aquatic Marine is a Knoxville, TN fish store with a reputation that reaches well beyond the city — customers drive in from across East Tennessee, and even from London, KY, for its livestock. Owner Kinny built the business up from selling fish out of his garage, and today the shop carries one of the deepest aquarium selections in the region, with both freshwater and saltwater systems kept in clean, well-maintained tanks. On the freshwater side, shoppers come in for rummy-nose tetras, bettas, plecos, axolotls, and an albino rainbow shark for sale in Knoxville, TN, alongside a wide variety of nano fish.
The live plant section earns repeat praise, and the store stocks aquascaping rocks, driftwood, and natural hardscapes that make it a destination for planted-tank builders. Saltwater hobbyists will find corals, reef fish, invertebrates, and snails available, and the team happily takes special requests for hard-to-find saltwater fish. Dry goods and aquarium equipment round out the inventory at prices reviewers say are comparable to the big-box stores but with noticeably higher quality.
RO water is available for purchase — a real help with Knoxville's hard tap water — and refrigerated bacterial starters are kept on hand for cycling new tanks. Staff members like Isaac, Matt, and Brandon come up by name again and again for walking customers through water chemistry, coral care, betta health, and full tank setups without any pressure to buy. Beyond retail, Aquatic Marine handles custom tank design, installation, maintenance, and tank moves for aquarists who want a full-service operation.
For Knoxville fishkeepers after healthy livestock, solid gear, and staff who genuinely want you to succeed, Aquatic Marine has earned its standing as the area's go-to aquarium store.
