Koi are ornamental domesticated fish that are descended from the common carp or Cyprinus carpio. Koi were first bred for their colors around 1820 in a town called Ojiya.
Different koi varieties are distinguished by their scalation, patterning, and coloration.
Koi and goldfish are different in that they were bred from a different species of carp. Offsprings that result from breeding a koi with a goldfish are sterile.
