I definitely have a predator. Fish are disappearing like crazy and it’s always the expensive ones. I’ve always had goldfish, they seem adept at dodging whatever it is that’s after them, but anything light in color disappears. I’ve seen raccoon tracks on my deck near the pond, but nothing ever appears disturbed in or around the pond itself. I saw a grey herring pass by the other day, but that’s not unusual. Fish seem way more spooked than usual. Anyway, I’m certain is coons or a bird, my question is, has anyone had success in preventing this? I have adequate cover as far as lily pads and several built in caves for hiding. Kind of at a loss. I can’t keep stocking my pond which basically leads to feeding a predator filet mignon. Thanks for reading.
