I did not use the background that came with my terrarium, because I like to be able to see into the terrarium from all sides. It sits on the snack bar in between my kitchen and dining area. Do the frogs "need' something so they're not out in the open? Or are those backgrounds strictly for looks. I think I can fill up the terrarium with taller plants and vines or branches, without using a background unless it is better for the frogs.
