Carp, along with many of their [[cyprinid]] relatives, are popular ornamental aquarium and pond fish.

Ornamental goldfish were originally domesticated from their wild form, a dark greyish-brown carp native to Asia, but may have been influenced by ''[[Carassius carassius]]'' and ''[[Carassius gibelio]]''. They were first bred for color in China over a thousand years ago. Due to selective breeding, goldfish have been developed into many distinct breeds, and are found in various colors, color patterns, forms and sizes far different from those of the original carp. Goldfish were kept as ornamental fish in China for thousands of years before being introduced to [[Japan]] in 1603, and to Europe in 1611.<ref>{{cite web|url=http://www.bristol-aquarists.org.uk/goldfish/info/info.htm |title=Goldfish history, colour and finnage, diseases, how to keep them, and how to breed them |publisher=bristol-aquarists.org.uk |access-date=2015-01-18}}</ref>

[[Nishikigoi]], better known simply as koi, are a domesticated varieties of [[common carp]] and [[Amur carp]] (''Cyprinus rubrofuscus'') that have been selectively bred for color. The common carp was introduced from China to Japan, where selective breeding in the 1820s in the [[Niigata Prefecture|Niigata]] region resulted in koi.<ref>{{cite web |url=http://www.mpks.org/articles/RayJordan/KoiHistory3.shtml |title=Midwest Pond and Koi Society – Koi History: Myths & Mysteries, by Ray Jordan |publisher=Mpks.org |access-date=2010-07-29 |archive-url=https://web.archive.org/web/20090723111340/http://www.mpks.org/articles/RayJordan/KoiHistory3.shtml |archive-date=2009-07-23 |url-status=dead }}</ref> In Japanese culture, koi are treated with affection, and seen as good luck.<ref>{{Cite web |last=Goto |first=Mao |date=November 24, 2021 |title=The History of Koi and Their Meaning in Japan |url=https://blog.japanwondertravel.com/koi-fish-japan-29657 |url-status=live |archive-url=https://web.archive.org/web/20230524172209/https://blog.japanwondertravel.com/koi-fish-japan-29657 |archive-date=May 24, 2023 |access-date=July 27, 2023 |website=Japan Wonder Travel Blog}}</ref> They are popular in other parts of the world as outdoor pond fish.<ref>{{Cite web |date=May 25, 2020 |title=Japan's Koi fish gaining popularity around world |url=https://www.aninews.in/news/world/asia/japans-koi-fish-gaining-popularity-around-world20200525181855/ |website=[[Asian News International]]}}</ref>
