Stan:
Great Question!!!!! Until this past weekend, we thought our small pond contained females only, then our Ochiba spawned and we suspected the Ai goromo to be the fox in lambs clothing... Then the next morning all the koi were chasing each other and some of them spawned... The Goromo, which was chased the most, looks a lot thinner, once again, foam and eggs all over the place...
The only koi to stay out of the action was the Ochiba which spawned first...
I have the same question, "do females also chase"...these koi are all 22" plus...
