That range is no where near as wide as all snakes use in real life. Every day in nature its either too cold, too hot or most commonly both. Behavior and adaption is what allows them to exist in those temp ranges. As long as you support them in a way they can make decent decisions, they will perform at their best.

So far, its my opinion that hognose are much more shy then kings. Kings are more prone to positive training. But then, I am just learning hognose. They are indeed a unique snake. Best wishes
