My sense of humor is tough skinned. And, I realize that no one could possible have a real answer to this question. You'd have to be a fish to know. But, I wonder if anyone else has seen fish exhibit such an accurate sense of time? I first thought they must be sensing some sound transmitted into the water by the legs of the feeder. So, I moved the feeder back until it's legs were completely out of the water. It's not on a dock. It's a modified deer feeder with a directional throw timer mechanism that I use for feeding the fish.

I'm stumped!
