Tucked away in Cookeville, Tennessee, Tri-Star Koi is a by-appointment koi dealership run by Marlon, a dedicated hobbyist-turned-dealer whose passion for the fish is immediately apparent the moment you step onto his facility. This isn't a walk-in pet shop — it's a curated operation built around sourcing and selling high-quality koi, with Marlon personally traveling to Japan each year to hand-select the fish he imports. The facility houses a wide variety of koi across multiple price points, and reviewers consistently note that his pricing is competitive despite the caliber of fish on offer.
Marlon has done extensive research into koi nutrition and stocks food and supplies he's vetted himself, making Tri-Star a one-stop resource for pond keepers across Tennessee and beyond. Orders are filled and delivered quickly, and Marlon is known for responding promptly to inquiries. What truly sets Tri-Star Koi apart is Marlon's deep involvement in the koi community.
He's active in supporting koi shows, presenting to local and regional clubs, and sharing knowledge on social media. Multiple customers describe him as someone who takes genuine pride in the health and quality of every fish he sells, and his willingness to spend time answering questions — no matter how basic — earns him repeat business from hobbyists at every level of experience. Visiting Tri-Star feels more like consulting with a trusted expert than shopping at a store.
Marlon walks customers through their options, discusses pond readiness, and ensures buyers leave with the information they need to keep their koi thriving. Several reviewers mention purchasing from him repeatedly, a testament to the trust he's built. For pond enthusiasts in the Cookeville area or anywhere in Tennessee looking for Japanese-imported koi, quality koi food, and genuinely knowledgeable guidance, Tri-Star Koi is worth the appointment.

We absolutely love Tri Star Koi. Marlon is such a hard worker and he's very honest. We've bought many from him at this point and will continue to do so. He's passionate about what he does and he cares about the koi and their health. He has done his research on what's the best food to feed to grow fantastic koi. I cannot speak highly enough about Tri Star. It's always a pleasure working with them.

Had an amazing experience visiting Tri-Star Koi. The passion shown by the owner, Marlon, is very clear and evident. I didn’t leave with any fish (pond is 2-3 weeks out) but Tri-Star will be my main destination for Koi.
