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.
Step 1. Obtain an aquarium that is large enough to contain the number of koi you have. Koi need a large volume tank to thrive. Your tank should have 1 cubic foot per 1 inch of koi fish length. Multiple the tank's height by width by length to determine the tank's cubic footage. Put the aquarium on a stand that can support the weight of the tank, and find a location in your home that can accommodate the weight of the tank safely, such as near a support wall or on a concrete basement floor.
