Breeding Age

How old do the Koi have to be before they spawn....or breed? We've had ours for a little over a month and we now have a minimum of 17 babies....we have three 5-6" koi and two 4" koi.... - Tonya

Koi usually have to be at least 2 years old to spawn. Usually they are a little larger than yours, but you probably have small ones...
