The Exo Terra Reptile Fountain is a unique water dish that supplies your reptiles and amphibians with a continuous supply of fresh, clean, aerated drinking water. Many reptiles do not recognise stagnant water as a source of drinking water. The Reptile Fountains constant movement of water tumbling down from the rock, encourages reptiles to drink more, keeping them healthy and hydrated. The continuously flowing water raises humidity levels in the terrarium.
