I don't have a leopard gecko...yet, but I have been thinking about getting one. My questions: I have read on many care sheets that tile makes a great substrate and an under tank heater works well for them....Will the heat from an undertank heater go through the tile to provide warmth? Also will they eat the canned insects or do they have to be live...I ask only because I swithched my bearded dragon to canned after many trips to the vet for dewormings due to live insects. Thanks in advance for any replys
