Koi Fish Tank

Koi are large domesticated carp commonly kept in backyard ponds. Some koi are exceptional specimens, called "show koi" and can be very expensive. Many pondkeepers keep less expensive pet koi; they may not have perfect colors and markings, but they are great pets. There are many koi varieties available to the koikeeper, including Asagi, Bekko, Doitsu, Kohaku, Sanke, Showa, Tancho and Utsuri, and they all make great pets. When stocking the koi pond, make sure to provide at least 100 to 200 gallons per adult koi fish. Larger jumbo koi should be in larger ponds that have 1,000 gallons per koi.

Here’s a chart of the popular koi fish for reference. You’ll no doubt get to know the names even more intimately when you look at koi fish for sale, or at auctions
