Spooking off the rig underwater carp fishing

Here we have a clear spot near the inlet to the lake. It’s right next to a snag were the fish like to hold up, the snag is just to the right of the shot. I was learning how to lure fish from snags when I noticed this. Watch how the fish continually spook off the rig. They know something is wrong. They become aware of something but I dont think it’s the hookbait. What do you see?
