 Larger reptiles supplied with heat rocks often prefer to stay near their rock at all times, diminishing their novelty.Pet owners and keepers now usually recommended a non-direct contact UTH (under-the-tank-heater) or thermal tape which distributes heat through the enclosure’s substrate placed in different areas of the tank to create a more even heat gradient, making the pet more liable to move throughout its enclosure.Another popular solution is replacing regular lighting with UV-specific basking lights.
