Dennerle Ceratopteris cornuta
Easy, delicate fern that is often used in breeding aquariums. Beneath the leaves floating on the water’s surface is an ideal hideaway, e.g., for labyrinth fish to build their foam nests. This fern is very easy to look after. Strong light and CO2 supplementation are very helpful in encouraging growth and producing sturdy fronds. Above the waterline, the undersides of the leaves can develop small adventitious plantlets. These can be bedded into the substrate for propagation.
