Here is one for y’all. I have solar lights on pier shining into the water. There is one crappie that comes to the light and does something really odd. He stands on his head facing down and sort of spins around slowly and then moves over to do it again. Sometimes tail breaks the surface. Then moves to the other light and does it over and over again. What do y’all think it’s feeding on? Small BG eating bugs on the surface didn’t bother this fish and it made no move to catch bugs or bg…..any ideas?
