I run about 85*...and yes, 95* is way over-kill. I've kept corns for many years, they do NOT like it too warm. They seem to prefer low-70's most of the time, &
as long as they have additional heat (I prefer UTH for them) as an option, they'll be fine. I wouldn't worry between 85-88* as long as they have enough room to
be as close as they choose to the heat and can get completely away from it as needed. If using UTH, you should only heat about 1/6th to 1/8th of the cage floor.
