Description
Java Fern ( Microsorum pteropus ) is one of the most popular and beginner-friendly freshwater aquarium plants, prized for its hardy nature and distinctive green, leathery leaves. This slow-growing rhizome plant thrives when attached to driftwood, rocks, or other hardscape rather than buried in substrate. Its adaptability to a wide range of water conditions makes it an excellent choice for community aquariums, shrimp tanks, and aquascapes. Java Fern requires minimal maintenance and can develop new plantlets directly on its leaves, making propagation simple and rewarding.
