Ceratopteris thalictroides is a pantropical fern, 15-30 cm high and 10-20 cm wide..
This plant normally grows fast, but the addition of CO2 may be necessary to promote growth. 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.
