Exo Terra Rock Outcrops help create a more 3-dimensional habitat in all types of terrariums. A proper hiding area is a necessary but often underestimated feature of a natural terrarium. Without a safe spot to hide and sleep reptiles and amphibians will easily develop stress that will affect their activity and appetite. Hideouts often also provide shelter and or a cooler and moister area in the terrarium. The shape of the Exo Terra Rock Outcrop enables it to fit nicely in small spaces minimizing wasted space within the terrarium and generating basking areas closer to the top screen. It is very durable and is easy to clean. The multiple entrance holes turn this Rock Outcrop into a secure hiding space helping to reduce stress.
