Coco Soft™ Fiber is the ideal substrate for many arachnids and insects (including crickets!), dart frogs and other small to medium sized amphibians and tortoises. For many applications Coco Soft™ Fiber can be used underneath a moss or covering grass in high humidity amphibian and reptile enclosures. Made from fresh, 100% organically grown coconut husk, Coco Soft™ Fiber smells fresh up to 3 times longer than other reptile bedding by eliminating odors naturally with beneficial bacteria, rather than perfumes or dyes.
