Editing Cyprinidae (section)

=== Aquarium fish ===
Numerous cyprinids have become popular and important within the [[fishkeeping|aquarium and fishpond]] hobbies, most famously the [[goldfish]], which was bred in China from the [[Prussian carp]] (''Carassius (auratus) gibelio''). First imported into Europe around 1728, it was originally much-fancied by the Chinese nobility as early as 1150{{nbsp}}AD and, after it arrived there in 1502, also in [[Japan]]. In addition to the goldfish, the common carp was bred in Japan into the colorful ornamental variety known as [[koi]] — or more accurately {{Nihongo|2=錦鯉|3=nishikigoi}}, as {{Nihongo|2=鯉|3=koi}} simply means "common carp" in [[Japanese language|Japanese]] — from the 18th century until today.

Other popular aquarium cyprinids include [[danionin]]s, [[Rasbora|rasborines]] and [[Barbinae|true barbs]].<ref>{{Cite book|title=Aquarium Atlas Volume 1|last1=Riehl|first1=R.|last2=Baensch|first2=H.|publisher=Voyageur Press|year=1996|pages=410}}</ref> Larger species are bred by the thousands in outdoor ponds, particularly in [[Southeast Asia]], and trade in these aquarium fishes is of considerable commercial importance. The small rasborines and danionines are perhaps only rivalled by [[characid]]s (tetras) and [[Poeciliidae|poecilid livebearers]] in their popularity for [[Community aquarium|community aquaria]].{{citation needed|date=April 2012}} Some of the most popular cyprinids among [[aquarists]], other than goldfish and koi, include the [[cherry barb]], [[Harlequin rasbora]], [[pearl danio]]s, [[rainbow shark]]s, [[tiger barb]]s, and the [[White Cloud Mountain minnow]].

One particular species of these small and undemanding danionines is the [[zebrafish]] (''Danio rerio''). It has become the standard [[model species]] for studying developmental genetics of [[vertebrate]]s, in particular fish.<ref>{{cite book|title=The diversity of fishes|last1=Helfman|first1=Gene S.|last2=Collette|first2=Bruce B.|last3=Facey|first3=Douglas E.|date=1997|publisher=Blackwell Science|isbn=978-0-86542-256-8|location=Malden, Mass|pages=228|oclc=299475257}}</ref>
