Appliances generating heat for pet reptiles are always a thing of concern to reptile owners. Knowing that of all the heat-generating sources, heating pads or under tank heaters are among the safest types of heaters for captive blue tongue skinks. For one reason, they only get relatively low in temperatures sometimes, which means that much damage to skinks as a result of overheating is minimal. They're also resistant to water and do not emit any light, so you can have them as your only heating source operating all round the clock (24/7). However, do not forget to have a thermostat connected to it to keep temperatures ideal for your skinks. Finally, make sure you follow the user manual carefully.
