I'm planning my first vivarium build and am looking to house an emperor scorpion. I've heard it is not a good idea to put the heat pad on the bottom as they will burrow to escape heat. Instead the advice I've heard suggests putting it on the side of the tank. I have a 10 gal 20x10x12. My question: is it ok to mount the heat pad on the "back" of the tank behind the background? Say I had one of those cork bark background panels on the back of the tank and installed the heat pad so it was mounted on the left or right side of the back. Would that negatively effect the adhesive of the background, mitigate the heat transferred, etc etc? Or is it best to mount the heat pad on the left or right side panel of the tank? New to all this and just wanting to provide my future scorp with the best home possible. Thanks in adavance for any advice!!
