It looks perfect too me, Maybe more fishes or brighter background, but again it deserve at least top 500.
Maybe an background plant like cyperus helferi or some valisneria or even eriocaulon sp needle leef would looks nice going from right to left.
Nice tank, how much power of chihiros do you use?whats lighting regime?
I also wonder how much light.. Plant color is so nice and vibrant but the pictures looks a bit dark...
We need an FTS! 😀
