Suspended Bass

On my home lake I see suspend fish in front at the corner of boat docks : Not sure if it is bass my question is do we know how many hours a day bass sleep .? Do we know if fish are like deer and feed more at night . What is your opinion about dock lights to attract bait fish .? I feel like having to many dock lights on a lake hurts the daytime fishing because when the lights come on it makes it easier for fish to feed on bait fish .
