Very good article. I have two Leos in a 55 gallon tank on my enclosed porch. Although I have an UTH, I am thinking they don't move around the tank due to it being to cool; however, you guys say they are OK down to 60°F, so I will stop worrying about them. Have A Good One...jim
If it got below 65 F I personally would probably add a bit of heat, but really you should be fine down to 60 F and some people say even 55 F.
