Java fern

Java Fern (Microsorum pteropus) is a species of fern native to southeastern Asia. It has been introduced to other regions, and it is used in aquariums, both as a placed decoration and as a plant to add to the natural habitat. The species grows tall and the leaves can become quite elongated and can be allowed to cascade out of the water, or pruned and turfed. The leaves are green with light veins running through them. The fronds can attain a length of 18 inches in most cases. This species grows well either with or without an aquarium filter.
