When inside, and feeding on a regular basis, it is best to have a temperature of at least 70 degrees to aid digestion. A simple basking light is all that is needed. I use a 40 watt bulb.
:Ok some people were saying on the aol message board how painteds need some type of heeting. I belive this is wrong for all painteds except southern painteds. I have never used heat in the winter for my painted when he hibernated in the winter. In the summer he is in a pond. However in the wild painteds live here in Buffalo NY and when they are out it can still get cold here. What do u people think? And look im the first person with a real question here wow.
