Product Info

This particular listing of koi will consist of black karasu koi. If you would prefer a mix of colors, please view our other koi listings.

Koi are beautifully and uniquely colored members of the carp family. They are a great addition to any freshwater garden pond. There are two varieties of Koi available: Standard Fin Koi and Butterfly/Long Fin Koi. Standard Fin Koi have normal fins, while the butterfly koi have longer flowing fins. Koi come in a multitude of color patterns, from solid yellow color to tri-color patterns and everything in between. Toledo Goldfish strives to send you high quality koi with a range of color patterns. Koi can be mixed with other freshwater straight tailed pond goldfish. Koi are omnivores and will eat all types of dried and live food, but basic fish flakes or pellet food will provide the proper diet. Please note the pictures shown above are a good representation of our fish, but not the exact fish you will receive.

Born and Raised in the USA
All Toledo Goldfish live fish are born and raised on a family farm in the USA. Our farm locations and fish are health certified to insure you are receiving a quality product.

Phenomenal fish

Once again toledogoldfish exceeded my expectations and delivered a great selection of beautiful koi. Sent me an extra one and both standard and butterfly. Little did I know my wife was surprising me with 5 as well. So we are now the proud owners of 13 beautiful standard and butterfly koi. Can't go wrong with toledogoldfish, all fish have been here a week and are doing great!
