Hi MellyJoe. For warmth I have a small heat mat (8w) under the tank, with lots of ventilation. lighting wise he doesn't seem to mind a lamp on the other side of the room, as long as it's not too bright. He also doesn't mind the red light in short spells but I'd suggest leaving it off if you want him to get up at night.

Is he warm enough through the day? I believe if they are too cold they won't eat much. How long have you had your frog?
