Koi (Cyprinus rubrofuscus) are the centerpiece fish of ornamental ponds and water gardens worldwide, selectively bred in Japan for over two centuries to develop the bold colors, patterns, and metallic finishes that define each variety. Our koi for sale collection features both pond-ready domestic koi and premium imported koi, including classic Kohaku, Matsuba, Kujaku, Yamabuki Ogon, Tri Color, and Black & White lines, along with long-finned Butterfly Koi in Mayan, Panda, and assorted patterns. Doitsu (scaleless), Ginrin (sparkling-scale), and AA-grade premium koi are also available for collectors looking for show-quality fish.
Koi are pond fish at heart and grow rapidly, often reaching 18–24 inches or more, so they require ponds with strong filtration, ample volume (typically 250+ gallons per adult koi), and protection from predators. They are remarkably long-lived — well-cared-for koi routinely live 25 to 50 years — and become hand-tame with consistent feeding. Koi tolerate a wide range of pond temperatures and are kept successfully in climates across the country.
Every koi is hand-selected for color, body conformation, and pattern quality, then carefully packed and shipped with our 8-day live arrival guarantee. Whether you're stocking a new water garden or upgrading to premium imported fish, our koi selection delivers quality at competitive pond-keeper pricing.
