Should I put the heat pad under the tank or inside the tank and put tiles as a substrate? Also should I get the heat pad that is for 60 gallon tanks or a smaller one? Also thanks for the reply.Is it cracked? If so, either remove the dark tape and replace with clear packing tape or get a background and attach it. You would set it up the same way as any other enclosure: heat pad on one side, a bunch of hides on the warm side (since you have the room), water bowl on the cool side, humid hide wherever you want it and other decorations wherever you want them.
