Well what should I do, Im always up at night with my computer on, but I have it pointing away from the tank, so there doesnt seem to be much light entering the tank. I turn my circulation PH on a a night cycle (off) with my filtration ones still working(so thereis no oxygenation loss. I find him at the surface or at the front of the tank closest to the light (Hes not gasping for air at the surface, he is just below it.)
