Water Sprite (Ceratopteris thalictroides/ cornuta).

You can grow it on the surface or plant it in the gravel. It's a good plant

Oh! I have water sprite in another part of my aquarium- it looks so different I thought that they couldn't be the same thing. Thank you!

Different species. One has broad leaves like in the picture, another species has finer leaves.
