Hello, so I am getting two Whites Tree Frogs, and I need some help with heating. I have two bulbs at the top, that do not produce much heat at all, and are used for vitamins for the frogs. I was going to get a heat pad, but after some research I realized ALOT of them were catching on fire and burning the tank and frogs. I don't know what to do now, and don't want to take the risk of a heating pad. Also, I need some substance for the bottom of the tank, and do not know which one would be the best. Thank you so much for your help!
