This tank really got my attention. It looks very wild and natural, like something I'd imagine being under the surface of a marsh. I would'nt want to drastically change anything about it really. I'd probably just add a few small scattered cryptocoryne in the foreground, some dark green type. Maybe fill in a little behind the stump with some tall vals. Really, that is a beutiful tank, I was curious of how long the tank has been set up.
