Hello. I recently adopted a baby snapper.. I am pretty sure it is a common. But my question is about heat. I know it has to be about 75-80 degrees in his tank, I leave his light on all day and it is the right temp, but what about at night? I know I can not use a black light. Does anyone have a suggestion as to what to use at night? (he is in my room and the reg light is too bring for me.) Thank you.
