ok, the tank either way is nice, my opinion is the old pic minus the bags of stuff of course. But the tall fake plants in the corners stand out too much, again in my opinion.
I would go med in the corners and make the tank look taller? I love the rest of the tank, top notch, just enough.
I know theres plenty of reasons to go plastic. I have some in my tanks. But some live plants, again in my opinion would look really nice. especially with the rocks.
