Zoo Med Repti Rock Reptile Water/Feed Dish adds a realistic rock look to your terrarium while providing safety and quality too. It is constructed of foamed polystyrene and does not release dangerous toxic residues into the water. Molded "stairs" prevent drowning of smaller reptiles and amphibians. Smooth non-pitted, non-porous surface will not absorb bacteria, stain or leak, making it a cinch to clean. Assorted colors - ships in random colors.
