Some of my koi have gotten quite large - 25" - 30+" - and they splash the food out of the feeding ring I use. I made it from a 3'diameter hula hoop and covered it with pipe insullation so it would continue to float. I also put some liner material around the edge of it that extends about 1" above the top and about 8" in the water below it to help keep food in it. They're too big for it now - they splash it out both over the top and underneath in their feeding frenzy. Any ideas would be appreciated. I don't want to have to continue stand out there with a net to scoop the food back into the ring to keep it from ending up in the skimmer! Any ideas would be appreciated!
This is an old picture but you can see the feeding ring and some of the fish which are quite a bit larger now.
