I have a 40 gallon tank. A heat pad underneath that stays between 89 and 92. The thermostat is placed directly on top of glass inside the tank where heater pad is. I keep humidity at 60 but since ive thought he was about to shed i bumped it up to 70. I use Eco Earth Loose Coconut Fiber Substrate. And the tank has a slide on mesh top. I have a seperate thermostat to regulate room temp and room temp usually is between 78 and 80. Been trying to keep that up while allowing for some fresh air. Theres no way it could be because didnt poop yet or because he may be getting ready to shed? Or both?
