Koi

The Koi is a rare fish found in rivers between 4pm to 9am all year round. It can be sold for 4,000 Bells at Tom Nook's Store.

Donating to the Museum
As with all fish in the series, the koi can be donated to the Museum, followed by a small talk by Blathers about it.

In Animal Crossing
"Some fish bring a higher price at the market than koi, but koi are special in some indescribable way... For whatever the reason, catching a koi feels like... like catching a living fortune, somehow. Interesting, that. Well, aren't I incoherent! All rambling aside, rest easy knowing we will give this noble fish the utmost care."

In Wild World
"Hoo my! This addition should improve attendance at the museum most dramatically! I suspect that with the addition of this marvelous koi to the collection, folks from all around < > will be flocking to see it, wot wot!"

In City Folk
"...Great hoo! One of these should liven up the museum nicely, that's for certain! I say, I've heard a koi's worth is determined by how flashy its coloring is... Hoo now... How many Bells might this one be worth? ...Hoo, compose yourself, Blathers. This is for the museum!"

The koi can be found in the middle-left tank, with other fresh water river fish.

Further Information
The Cyprinus carpio or 'Koi' as it is better known, is an ornamental fish of the common carp variety. They are usually found in private and public aquariums and they are mainly bred for viewing purposes. Much like the Goldfish, the Koi is also interbred from specially selected Carp. Unlike the Goldfish however, these are bred from common carp (Cyprinus carpio) and have a common body shape, but with different colours (the opposite of Goldfish). They are omnivores, feeding mainly on insects and algae. The name 'Koi' comes from the Japanese, simply meaning 'carp.'

Toy Set
The koi appeared in a toy set along with Purrl (a cat villager), an eel and a fish tank.
