Utsuri Koi
Utsuri Koi is a Japanese Strain that is black with red, white or yellow markings that semi-resembles a checkerboard. The black body is accompanied by one other color that is typically nor metallic. Koi can live 25 to 35 years (some even longer) in captivity if properly cared for and can get as large as 3 feet long, so they will need quite a large space made specifically for koi. Feeding multiple times, a day is recommended, since they are very active swimmers. Koi are very messy eaters, so be sure to monitor the water quality and perform water changes as needed. They will eat just about any pellet or flake that you offer, however, be sure the food has vegetable foods in it. Freshwater food with vegetables will help prevent swim bladder problems. They are considered diggers, so use caution when adding plants because they can get uprooted. Use large rocks to help keep the plants anchored down.
