No matter what your snake is in, you aren't going to see it 99% of the time. Ball pythons are a shy nocturnal species and hang out in their hides the vast majority of the time. Being in too open of a cage like glass tanks are tends to stress them out. Fish tanks just aren't made for snakes, they don't hold humidity or heat, they are poorly shaped, heavy and breakable. PVC cages or tubs tend to offer more security and are heated through heat mats/tape or radiant heat panels which doesn't suck the humidity out or be as much of a fire/burn risk as a lamp.

Those type of temp and humidity gauges are not accurate at all and they aren't telling temps where you snake is so pretty useless. I use accurate digital ones for a quick glance at temps, one probe on the hot spot and then put the rest on the other side to see what ambient is about but temp guns are the way to go to judge temps directly. Any source of heat needs to be on a thermostat to control it, that way temps aren't changing wildly and burning or underheating your animal. I use herpstats. As ball pythons don't bask a ceramic heat emitter would probably be better than one that emits light, they put off a lot of heat and need to be on a dimmer. The UV isn't needed at all. Couple identical tight hides as mentioned, feed in the tank, much more likely to get bit trying to move a hungry snake.
