Hi there! I just bought a 30gallon octogon setup with just one Chinese Mountain Lizard today and I need help with the heating. I know these guys do alright at room temp, but my house gets a little cool at night. I dont really want to leave the uv bulb on all night, but there isnt a set up for any other type of heat lighting so I was wondering about a under the tank heating pad. There will be some gravel on the bottom covered by a nice layer of bark. Do you think this will help at all at night for an arboreal lizard? I thought it could help with the humidity as well. Suggestions? Im going shoping in the morning to give the tank a makeover.
