Some years they spawn once or twice in spring. Some years they spawn on and off all summer. One year none of them spawned that we know of. I think that was the year 2002. My koi do not eat their fry and now that they're getting large they ignore most of the eggs as well.
A Koi can be kept in a large tank with a power filter, it will grow as big as the tank!! No, it will not eat other fish, but it will torment them. Koi will only play with the fish, some people look at it as picking on them but they only play. Sometimes the other fish dislike it but that cant be helped.
