Exo-Terra Feeding Dish Large - Length – 21.5 cm, Width – 18.5 cm, Height – 3.5 cm. Exo terra’s Water Dishes have a very natural and realistic rock finish on the outside and a smooth non-pitted surface on the inside. The bowls are coated to prevent the development of harmful bacteria and make it easy to clean. The neutral natural colour allows easy integration in desert, tropical or any type of terrarium. Smaller reptiles, amphibians and insects can easily escape out of the Water Dish by the ‘safety steps’ inside the bowl to prevent drowning.
