Plant Id - Grassy Foreground Plant

Hi all, I've got a couple of ideas about this plant but none of them seem to be quite right. Seeing as I want to buy more I'm going to need to figure it out Help?

Oh and please excuse the state of it, I planted it all wrong and have since spread it out so it should perk up soon I hope

Oh and if it helps, it spreads by sending out plantlets on long shoots, not that it's done that for me lol, but it did for the person who gave it to me.

that is echinodorus quadricostatus, it spreads really well when settled. Let it settle first, this can take a few weeks, but when it goes it goes.

Ah! See that was my first guess, then I kept looking and convinced myself it was echinodorus tenellus and THEN started to think it may be sagittaria subulata, lol thanks so much!

I have spread it out a little because it seemed to be suffering all clumped together like that, I hope that was the right thing to do!
