The Sumatra fern has much daintier leaves than Ceratopteris cornuta. It usually grows in muddy, shallow waters and somtimes in rice paddies. It needs enough space since it does grow very quickly. With medium light it's easy to look after and does not cause any problems. This is a popular beginner's plant and is suitable for anyone new to aquatics.
