I am going to go ahead and paste some info about them that I have posted in my own thread about by snake. Much easier than typing all of it out again.
By ambient temps I mean no hot spot, and don’t keep them at anything over 86°F. Sometimes people will say 90°F but that is too hot for them. Once it gets that hot outside most of the time they will be hiding from the sun, and staying in the shade. A lot of the time in their range (a large portion of the U.S. and in some of Canada) it won’t stay that hot for long.
