I've seen them up to 3' and herd stories of them getting bigger. Koi, a variety of carp and closely related to goldfish, tend to grow (or not) to match the dimensions of its habitat. So carp in rice paddies can become quite large, whereas carp or koi in small tanks will remain small.
I have seen many beautiful Koi over 36" but I believe they can get considerably bigger than that. Koi were developed from the wild, common (European) carp Cyprinius carpio by the Japanese in the 1800s. These wild carp can get to over 5 foot long and weigh over 80lbs.
Up to 36 inches(3ft) make sure that if you have more than one to have a nice big pond for it, like the ones you get at Walmart. 50-100 gallons are perfect.
Koi get anything from 2 foot to 4 foot long, they are huge chunky fish!
It all depends if they have enough food intake and water quality matters a lot. Have plenty of space and it will take about 3-5 years to grow into full size depends on breed of koi
around +24 inches
6 metres squered at least
90 lbs.
The size of the koi will depend on many factors such as what type of koi it is, how much and what you feed it and the size of the aquarium or pond you keep it in.

The kio would be to big. But it would try to attack it. Then they will fight. Dont put bettas with other fish.
The Japanese for Koi is nishikigoi.
The sex of koi fish cannot be determined unless a)you dissect the koi or b)you witness the breeding.
Koi fish is suitable as a feeder fish for other larger fish. If a human wanted to eat a Koi fish, (which in general unlikely), it would be better eaten dead.
