To meet growing demand for ornamental fish and water garden features across Central Ohio, Ohio Koi is constructing a 13,000-square-foot retail greenhouse that will open to the public in spring 2026.
The new facility, known as Mega-1, represents a major investment in the local economy and is expected to bring increased tourism and national attention to Delaware County. Once complete, the center will serve koi, goldfish, and water-garden enthusiasts from across the United States.
Over the past decade, Ohio Koi has become the Midwest’s leading breeder and importer of koi and goldfish, with record growth in 2025. Mega-1 will house thousands of koi and exotic goldfish valued in the millions.
The greenhouse will feature 34 in-ground tanks and ponds, ranging from 500 to 20,000 gallons, designed to accommodate large shipments of premium Japanese koi arriving in early 2026. Dozens of goldfish tanks will showcase 15 to 20 varieties bred on-site and sourced from premier breeders in Japan and across Asia.
Fish will be available in a wide range of sizes and price points, serving home pond owners, collectors, and commercial landscape projects.
Mega-1 will also include the Koi Lounge, a tranquil space where guests can view showcase koi while consulting with Ohio Koi’s pond design and construction specialists. Visitors will be able to explore material samples, view a portfolio of completed pond projects, and receive guidance on equipment, stonework, and aquatic plant selections.
