Common Name: Water Sprite 
 
Ceratopteris thalictroides is a pantropical fern from Asia, 15-30 cm high and 10-20 cm wide. In small, open aquariums, it can grow out of the tank and form beautiful surface leaves. The finely branched leaves are very decorative and provide good contrast to other leaf shapes. In good light Ceratopteris thalictroides grows fast and helps prevent algae by consuming large amounts of nutrients. This makes it a good starter plant in small aquariums.
