Black River Koi is a privately owned and operated business located in Columbia Station, OH, serving the greater Cleveland area. William Martin, our Koi specialist, entered the industry in 1998 and has since gained extensive knowledge on how to create and maintain the best environment for your aquatic ecosystem.


Our mission is to provide high-quality Japanese Koi and goldfish in a variety of sizes and colors at reasonable prices. We take great care in the selection of our fish and undergo a rigorous quarantine process upon their arrival from Japan. Each breeder's Koi is placed in separate quarantine systems, which are heated to above 50 degrees Fahrenheit for a minimum of two weeks. The fish are then tested for parasites before they are made available for purchase.


At Black River Koi, we also offer a variety of aquatic plants that can be purchased bare-rooted or potted. We take pride in our hand-picked selection of pond supplies and only carry products that we have personally used and know work well.

 Black River Koi is currently undergoing a significant renovation to improve our services. As part of this renovation, we are enhancing our pond supplies inventory while expanding our koi fish habitation area to include a new controlled greenhouse. We anticipate that this remodeling project will take a few years to complete in its entirety. If you have any questions or concerns regarding these changes, please do not hesitate to ask any of our knowledgeable staff members for assistance.
