I know that cresteds dont need "heat" but I was watching a utube video and saw one person with flexwatt along the back of the tank. If it gets in the 60s in the house this winter would that be a good way to go to keep the temps a bit higher?
I wonder if they would use it if I kept it at maybe 78 degrees?
