In sticking with the "euro" theme I thought it was appropriate. Clay backgrounds look great but I'm not convinced that they'll stay in place long term (or rather, that I could build one that would stay in place). Since this tank is meant for testing all of the features I'll be using in the big tank I wanted to go with something simple for the background.

All of my favorite European tanks use either tree fern panels or an equivalent, and they look awesome when grown in, so I'm not too worried about it
