Java Fern (Microsorum pteropus) is a beautiful addition to the freshwater, planted aquarium. Growing around 8 inches tall, with creeping, green rhizomes, Java Ferns are well suited for not only planted aquariums, but also those that contain cichlids and other large South American fish.
Java Ferns will do well if planted in moderate light as well as in a shaded area. It is amphibious, meaning that it will grow either partially or fully submersed. Provide at least 2 watts per gallon of light supplied by full spectrum (5000-7000K) bulbs.
Java Ferns will thrive in an aquarium with an alkalinity of 3-8 dKH and a pH of 6.0 to 7.5. They will propagate by adventitious plants on leaves & roots, and rhizome division may also be seen. Java Fern looks great planted singly, or in groups if there is enough room in the aquarium.
