The background is Aquaterra rainforest. It's a hard shell of some type over foam. I don't know if they could break through the top layer, but if they can bite driftwood, it's possible. I do have some driftwood, but there's nothing else in the tank, everything is in the sump. Here's a pic of the background before I filled up the tank.
