Dennerle Microsorum pteropus
Java Fern is the most popular type of fern with aquatics hobbyists, and is widespread in tropical Asia. This species varies widely and displays a number of different leaf shapes and sizes. A completely undemanding specimen and a perfect plant for beginners, it grows best when the rhizomes are anchored to rocks or driftwood. Low to moderate light is completely sufficient, although it also grows well under strong lighting. Older leaves can sometimes produce plantlets that can easily be cut away and reattached at another point using a piece of thin fishing line.
