Exo Terra's Desert Terrarium Sand is natural real desert sand with no added dyes or chemicals. The sand has been sifted to remove impurities and to create a wonderfully fine, soft texture.
Using natural sand in your desert reptile or invertebrates's habitat creates a natural and attractive desert environment that functions like one, too. Sand is an excellent heat conductor, stimulates natural digging and burrowing behaviors, and helps combat egg binding by providing a ready egg-laying substrate.
For best results, provide 2-6" of substrate, depending on the size of your pet.
