Buy Koi Fish Online

The Fish Collection's koi collection brings together some of the finest Nishikigoi available outside of Japan — hand-selected specimens bred for the vivid coloration, precise patterning, and robust body conformation that define championship-caliber koi. Our inventory spans the most celebrated varieties: the bold red-and-white Kohaku, the tri-color Sanke and Showa, the metallic brilliance of Ogon and Hikarimuji, and the ethereal platinum glow of the Gin Rin class. Whether you are stocking a new pond or adding a show-quality centerpiece to an established collection, every koi we offer has been evaluated against the same criteria used by Japanese breeders at the All Japan Koi Show. Koi keeping is a pursuit measured in decades, not months. These fish can live forty years or more and reach lengths exceeding three feet in well-maintained ponds. They require a minimum of 1,000 gallons per fish for proper development — serious collectors maintain ponds of 5,000 gallons and above — with robust biological filtration, aeration, and regular water changes. What they return for this investment is a living garden of color that deepens and evolves with each passing season, a fish that feeds from your hand and develops a genuine bond with its keeper. Every koi in our inventory is quarantined for a minimum of twenty-one days upon arrival at our holding facility. During quarantine we treat prophylactically for Koi Herpesvirus exposure, bacterial infections, and parasites including costia and trichodina. We verify appetite, inspect skin and gill condition, and evaluate color stability before any fish is approved for sale. Koi ship in oversized, oxygenated bags inside insulated containers with temperature packs sized for the transit duration and seasonal conditions. Our 100% live arrival guarantee covers every koi we sell. The Fish Collection is the trusted source for serious koi collectors who demand verified quality and safe delivery.
