Since the big koi have been moved out of the original pond, the little koi have all come out of hiding and are now swimming around in the open all the time. The three large butterfly koi still share their pond but the little koi do not seem to be bothered by them. Unfortunately, I had three little koi fall ill and die this past week. They did their little thing of hanging out by themselves in a corner of the pond and once I took them out, they died within 24 hours. The remaining koi were given some medikoi along with their normal food and all seem to be okay. Meanwhile the big pond cleared up while we were away and the big koi are swimming all over the pond. One must be part salmon since I saw her trying to swim up the waterfall. They enjoy hanging around the new water lily plants.
