The Exo Terra Water Well provides reptiles and invertebrates with a constant source of clean, fresh water. The small basin prevents the animals from fouling or spilling the water, while a screen prevents insects or smaller reptiles and amphibians from entering the reservoir. The natural rock-like finish makes the Exo Terra Water Well easy to integrate into any type of terrarium setup. Water evaporates quickly in hot terrariums and since terrarium inhabitants have the tendency to spill or foul their water dish, it is necessary to change or refill the water dish on a daily basis. The Exo Terra Water Well eliminates this problem by providing a constant source of fresh, clean water while its reservoir protects the water supply from reptiles and insects.
