The Exo Terra Rock Back Panel for terrariums is easy to cut and has a surprisingly natural appearance (1). It creates a multi-dimensional environment, ideal for reptiles to climb on or can simply be used to brighten up the terrarium. Its color and texture, like all Exo Terra terrarium decorations, blend seamlessly into the environment, whether humid or dry (2). The grooves on the back panel are designed to conceal cables or tubing for pumps or the Heat Wave Rock. The back panel is made of black polystyrene, so it won't be noticeable if accidentally damaged.
