Java Fern is a hardy freshwater plant with long, green, leathery leaves that add a natural look to aquariums. It grows best when attached to driftwood or rocks rather than buried in substrate, as its rhizome can rot if covered. It tolerates low to moderate lighting, doesn’t require CO₂, and thrives in a wide temperature range (20–28°C). Slow-growing but very resilient, it’s a favorite for beginners and aquascapers alike.
