I am planning out a 30 gallon vivarium for a small group of Anoles and I am looking some feedback on an idea I've got. The floor of the enclosure, according to my "vision" as of now, is going to have a waterfall and small pond incorporated with a false bottom. Because I will need a secondary heat source (especially for night) I was thinking, what about just heating the water? Logically, it would keep the enclosure warm and humid at night (and during the day) right? Any input would be appreciated. Thanks!
