Just a small point...Do intend to fasten the rocks together...ie: super glue or quick zip ties or something to that nature? The reason I ask is that those rocks are stacked pretty high and I would hate for them to fall and crack your tank. You cannot believe the strength an Urchin has at going between rocks and knocking things over.
