First of all, idk how you can put surviving and thriving in this situation because you have no idea if in animal is in a survival situation or in a thriving position. I'm just stating that my ball pythons were kept in these certain conditions, 89-91 degree hot spots with 65-75 degree cool spot and 40-60% humidity with regular feedings a week, without any problems. These were how I kept my ball pythons hatchling to adults without problem.
I dont know if this would be anything similar but in one other case with bp husbandry is the size of the tubs for different snakes. I've seen people put their hatchlings into 41 qt tubs and have had no issues. This is a problem to people because the cage is too big and stress the animal, others think that it will be better for the animal because it will acclimate to that enclosure. IN other cases I've seen people put adult ball pythons, male and female, in 28qt tubs and have no issues because some think smaller is a bit better for feeding responses. Another case, incubators where people think they have to be exact with the temperatures. I've seen numerous people use regular thermostats and even dimmers rather than proportional and have had great success.
