Hello, I am curious as to what materials you can use to build the background in a Vivarium... Um, I was reading about a kind of foam people use... But what kind of foam is it? A special foam? Also, would I be able to just use cork, like, from a cork board to create a #-D background and just blend the edges with coco fiber or something of the sort? Or would the corkboard material rot?
Any help regarding building the backgrounds and what materials that can be used successfully is a big help...
Thanks a lot...
