I feed my guys and gals in there enclosure with tongs about an hour after lights out and once the temps drop a few degrees. And the only light in the room is abit of light that comes through the crack in the door from the other room, just enough so I can see were they are. I have never had a problem doing it this way and I have been doing this routine since they were all babies. They are nocturnal so the best time to feed is at night in the dark, not saying you cant feed during the day but you will more then likely get the best feeding response at night.
