Any suggestions for this 5g

I think a dark blue background would look cool. The plants kind of blend in to the green. Blue would look very realistic, and contrast with the plant colors. Oh, and some cherry or bumblebee shrimp would be cute!
 
Yeah, the bookshelf is too narrow to put them at the back, but I replaced them with an internal filter--also I had some free time so the green tank went a little disco ;)

I really like the added rock, really looks nice.
 
What happened to the Windelov Java Fern? That was my favorite plant in your tank.
 
The java fern was really growing big so I moved it to my 10g. It is my favoriate too but I didn't want to prune it to make it fit. I will try and get some decent shots without reflections later :)
