My goodness this tank has come a long way and it looks AMAZING! keep it up! I really like the natural feel, and for me the rock in all the grass makes it, draws my eye first. I do think you should make it a little bit more visible IMO, but it looks great regardless. Those sailfin mollys help a bunch for algae, I just got one, works spectacular.
I never could get that pesky hair grass to grow worth a crap :-/
