Need plant ID plz

[Timmain42]

So I've got this so far:

Rasbora Hets
Glosso
Pygmy Chain Sword

But what are the tall plants in the background?!?

I may have the opportunity to do a composition like this one, but it's not going to be as effective if I can't find out what those plants are.... HELP?

looks like a hair grass of some sort; an eleocharis species. There are over 100 varieties though, so it can be very hard to differentiate. I was going to say just regular hair grass (as opposed to dwarf) since they are the most prevalent (and even then, they are not always the same strain) but I'm not sure about the height of that plant. I guess it could be...its just a little hard to tell since its in the back and whatnot.
