The Exo Terra Waterfall can be installed anywhere in a terrarium. Water circulation is provided by the Exo Terra Repti-Flo pump (included). The presence of clean and fresh water is important for the proper care and maintenance of captive reptiles and amphibians. Exo Terra offers a complete line of products to ensure that a quality water source is always easy accessible for the terrarium inhabitants and that the water is kept clean and free of debris. The Exo Terra Waterfall consists of several parts to facilitate easy cleaning. With its unique design, the Exo Terra Waterfall adds a touch of natural beauty to any terrarium while performing the vital function of providing a water source. For safety reasons, the walls of the collection tank are rough, in order to allow reptiles and amphibians to climb out easily, thus avoiding any danger of drowning. As an additional safety measure, for smaller chameleons and frogs, small stones or gravel should be added to the collection tank.
