i'm not sure about the background you know ?
i have seen some different things on the web,and i just don't know
if to buy a desert backing,or have a go at some of the amazing ones
that people have made.and try myself.
what would you put in there ?
i couldnt tell you the habitat of these things but i personally would make some sort of setup where live plants can grow. since you mention desert, maybe cacti? a tall dune grass in the back? im just thinking outloud.
