Thanks everyone! The reason I ended up with #1 is miscalculation on amount of rocks I needed for this setup. I had various LRs and base rocks, about over 100lbs, and I was determined to use them all, while building tunnels for fishes to hide and feed secure.
I wish I had done this sooner, and I like more open scape a lot better. Now it looks like it's ready to accept few more fishes (have a couple waiting in QT).
