shredded lily pads!! Help!
Hello everyone. I have a small 350 gallon pond in my backyard. Lately I go out and I have shredded lily pads. Little pieces floating everywhere. Thought maybe the cats were fishing, but noticed that even out in the middle, where they can't reach is damaged. I have 1 koi and 1 butterfly koi, 1 pleco and several run of the mill goldfish. I have included a pic of some of the damage. Has anyone had this happen? Any info would be helpful. Thanks in advance!
