I really don't have a light solution for today.... there is a plastic strip thermometer on the side of the tank that reads about 79 right now.

How about this? I have a space heater in one of the other rooms here.... I can bring it in and let it run all night and that should help right? It will be about a foot away but still should help a little bit anyway.

Also, this is in an office and I have multiple fluorescent ceiling lights in here (5 to be exact). It is usually warm in my office compared to the rest of the building.

I hope he's okay

I'm not going to worry about feeding him until I am confident he is comfortable. I would like to take him out so I can lay newspaper down, because right now he is laying on sand, pretty much. I'm afraid he will bite me however, so I think it's best to just let him be for now.
