Please ID this plant

I think that's Indian Fern -Ceratopteris Thalictroides
Not sure if it's known by any another name...
I have a ton of it in my tank. It's a cool plant, but keep up with it. Grows fast, it breaks off sprouts that float, grow and shadow the tank.
 
Wisteria is the closest from the images that I have seen, but these plants have broader leaves.
Any idea?
