Zoonoo, is that plant growing out of a bulb? If so it's an Aponogeton as Thunderloon says. As the fronds die off, clip them off close to the bulb. It'll go on like that indefinitely.
In the mean time you might want to look into getting Anubias, Java fern, Java moss, Wisteria, even a mossball as good low-light, easy-maintenance beginner plants.
Check out Mo's plant sticky ^up there, somewhere.
