Sorry all my posts here are me being stressed, haha. I know this isn't normal behavior, though, so I'm worried. I have a hatching that just arrived today who is adjusting. I'm leaving him alone but can still glance over and see how he is doing. I've caught him opening his mouth a few times ("yawning") which I've heard could be a sign of a RI. Could he just be stressed? Since I did just get him today, should I wait to know I'm not stressing over nothing?

My hot spot is at 90F and my cooler side is at 77F with around 85 in the middle. I am using a UTH with a thermostat as well as a CHE (because the ambient gets a bit cold this time of year). My humidity is a bit low, hovering between 45 and 50% which I plan on addressing after he is more adjusted.

TLDR; Got a ball python today and noticed he opened his mouth in a "yawning" fashion a few times (3 or 4 over the span of an hour or two). Could it be due to the stress of the new home or is it the start of a RI?
