i figured that out after i bought evryting for her. i have a year old ball in a 20 long. i thought about switching them since hes bigger. i just got him yesterday so he hasnt been in there long, i dont want to handle him yet since hes stressed. im using a heat lamp with a night time bulb for both tanks. I have a thermostat on both sides of the tank that reads both temp and humidity. I have aspen bedding with 2 bowls of moss on each side. I also have a uth that im not using it doesn't work with this big of tank plus shes almost always up on the plants I have on the walls of the cage.
