I got my ball python and I'm so worried about his heat. My room is cold and I have an under the tank heater and I have a thermostat with it. What temp should I set the under the tank heater to? I also have a heat lamp that is set to a thermostat to keep the air temp warm other wise it's freezing. If i have my heat lamp set to 90 and it makes the cage 99 could that affect the temp for my under the tank and make that lower cause the lamp made the tank 90 degreess? If i put my hand on the floor of the tank ever the heater is it doesn't feel very hot
