Plant ID please.

Hi, can anyone tell me what's the plant on the video below, the one with the thin leaves that looks like dwarf sagittaria?

I would say a Helanthium, former Echinodorus. Perhaps a small Helanthium bolivianum latifolius...

Thanks Yo-han.
I certainly didn't order any plant like this. I did order 4 species of echinodorus but they are all accounted for, and 2 species of crypts, one is accounted for. This one, I've no idea what it is.
They were all grown emersed and then melted and regrew. At the moment I am missing a cryptocoryne Mi-Oya and I ended up with this instead. I guess they sent me the wrong stuff.
It grew runners as well, so echinodorus of some type, oh gosh..
Is it a midground or foreground plant?

 

[Yo-han]

If it grows runners, than I'm quite sure it is a Helanthium. If it is latifolius, than it grows between 6 - 12 inch depending on conditions.

Here I used it in two of my scapes:
right from the middle:


the big one on the left:

Wow, it can grow big. Thanks for the pictures Yo-han. You've got some lovely tanks.

I currently have it in the middle kind of, as I was expecting it to be a mi oya crypt. If it grows that big I guess I'll leave it there and see 🙂

Just so to confirm the identity I got a picture of that plant when grow up. What is it exactly do you think? It does grow runners with the same shaped plant but small version. The adult plant's leaves are about 15-20cm long.
Sorry for the bad quality
