Do you mean that you have 1 rack? Or are there multiple snakes in one enclosure? Ball pythons need to be house individually - so just checking. Also, how is your tub heated? Just a UTH may not have the power to keep the ambient temperature high enough.
Its just a single tub he is using now.. He just got his first snake. He has been on here for a month researching and asking 99 questions.. Hahahaha. He has about 100 threads going and just needs to slow down a little to understand better.
