Add Realism to Your Reptiles Habitat With Repti-Rock Water Dish Realistic rock water/feed bowl adds a more natural look to your terrarium while providing safety and quality too! Constructed of foamed polystyrene! Does not release dangerous toxic residues into the water. Molded "stairs" prevent the 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. Will not break when accidentally dropped!
