@Kaorte: I have a rock looking hide, and a little cardboard triangle like hide. I do use a heat lamp. I don't have much of a choice as of right now. My room faces all the wind that hits the house. And even though I put the tank on the inside wall of my room, it's still cold in here. So I need to use it to keep up her temps.

@Pavlovk: It's dropped down since the first post. I'll do the plastic and tin foil thing. Thanks.

@Snakecharmer: I'll try your thing if the other two ideas don't work. Thanks also.
