Real-world information
The koi is an ornamental fish of the common carp variety, or Cyprinus carpio. They are found usually in private and public aquariums and they are bred mainly for decoration. Much as the goldfish, the koi is also interbred from specially selected carp. Unlike the goldfish however, they have a common body shape, but with different colors (the opposite of goldfish). They are omnivores, feeding mainly on insects and algae. The name koi comes from the Japanese コイ, pertaining to the common carp—the Japanese term for koi is nishigikoi (錦鯉), which literally means "brocaded carp".
