Natural looking water bowl The Exo Terra Water Dish is not only ideal as a water source but also a wonderful visual addition to terrariums. The water dish is made of food-grade resin and is carefully made to resemble natural rock. The outer surface is irregular and resembles natural rock while the inner surface is smooth and non-pitted. The special coating makes the bowl non-porous and prevents the growth of harmful bacteria. It also makes cleaning the water dish really easy. The water dish comes with "safety steps" on the inside to facilitate climbing out and prevent smaller reptiles, amphibians or insects such as crickets from drowning. It is extremely robust and sturdy, making it almost impossible for heavier animals to tip it over.
