"Koi" can also mean a virtual pet species in Neopets. , or more specifically (, literally "brocaded carp"), are ornamental domesticated varieties of the common carp Cyprinus carpio. They are believed to have originated from Eastern Asia, Aral, Black and Caspian Seas. Earliest records of Koi have been found in China and have been widely spread in Japan. The ornamental cultivation of carp flourished under the Chinese Qing Dynasty and Japanese Edo Period. They are very closely related to goldfish and, in fact, the style of breeding and ornamentation has become very similar, probably through the efforts of Japanese breeders to emulate goldfish. Koi and tattoos of koi are traditionally considered lucky.
