I have a female crestie I keep with me at school. Usually my room is kept between 70 and 75*, but my parents like the temperature at around 65* when I'm home. Last winter it was too cold for my gecko, so I pushed his tank right up against the electric heater panel and he would stick to that side of the cage because it stayed nice and warm. Anyways, this winter I think I would like to buy a heat source, which I'm guessing will probably be a heat lamp of some sort. Can anyone give me more info about the type I should look into and a bulb that would work? I'm thinking I could put it on one side of the tank so he could get away from it on the other side if it gets too hot. I think he was fine last year against the heater (He eats a good amount when he is happy, and hardly eats anything when he is not), but I still worried a lot about him. I feel like a heat lamp would give me a piece of mind. ETA: I'm pretty sure it's female, but when she was a baby I named her Marcus, so I tend to call *her* a *he*.
