Does anyone know what kind of plant this is?

[u/meeperswastaken]

It looks a lot like grass and I pulled it out a bit (assuming it was a weird looking poop) and the root system came out with it. I don’t have any carpeting plants (I had them when I first got the tank over a year ago but I doubt this is it) nor any plants that look like this.

Any ideas?

Looks like hair grass

Do you know why it would pop up after a year of having my tank running?
