the bait that comes to our lights are shad minnows. usually they are of various sizes with the smaller ones at the surface around the lights and the bigger ones seem to be deeper or near the surface out in the dark away from the lights .. i dont know if the lights attract shiners or any other type of minnows deeper than i can see. i cant remember ever seeing any if they do. from what ive seen, the bait minnows that come to the lights are shad. it would be interesting to see what is actually swimmin outta sight in the water below the lights
