- Not to be confused with Goldfish.
Koi are a species of fish (specifically carp) that live in ponds. They used to be bought as a pet in the Pet Shop. Wild Koi are not seen during the game, so it is unknown as to where the Pet Shop gets them, like the parrot.
- There was a Koi Fish Pin. This koi, unlike other koi of Club Penguin, has eyes.
- During the Medieval Party 2009 and Medieval Party 2011, many Koi fish were swimming on a fountain at the Lodge Attic. You could also feed them.
- They appear in Koi Ponds.
- Koi could have been brought to Club Penguin by Rockhopper (as well as the parrot, goldfish, and turtle). This is because Rockhopper Island is a tropical island, in which he could have bred these creatures.
- The Koi in Club Penguin have very small eyes.
