Java Fern ~ Microsorum pteropus

Java Fern (Microsorum pteropus) is one of the most popular freshwater aquarium plants, prized for its hardiness, low maintenance, and ability to thrive in a variety of conditions. Native to Southeast Asia, this slow-growing plant has long, leathery green leaves and can add a lush, natural aesthetic to any aquarium. Its adaptability makes it an excellent choice for beginners and experienced aquascapers alike.

• Type: Rhizome plant
• Size: 8-14 inches tall, 6-8 inches wide
• Light: Low to moderate (6-10 hours daily)
• Substrate: Not required; attach to driftwood, rocks, or decorations
• CO2: Not necessary but may enhance growth
• Water Requirements: 68-82°F, pH 6.0-7.5, soft to moderately hard water
• Growth Rate: Slow to moderate

Java Fern is easy to care for and thrives when its rhizome (horizontal stem) is attached to hardscape elements such as driftwood, rocks, or ornaments. Burying the rhizome in substrate can cause it to rot, so it’s essential to keep it exposed. This plant grows well in low to moderate light, making it ideal for low-tech aquariums or tanks without specialized lighting. It absorbs nutrients directly from the water, so no substrate is necessary. For optimal growth, ensure clean water and consider adding liquid fertilizers if the plant shows signs of nutrient deficiencies.

Java Fern is perfect for creating natural aquascapes and providing hiding spots for shy fish or fry. Its tough leaves make it resistant to most herbivorous fish, making it a suitable plant for tanks with species that tend to nibble on plants. Its slow growth means it requires minimal maintenance, although occasional removal of dead or damaged leaves helps keep it looking its best.

Interesting Fact: Java Fern reproduces through adventitious plantlets, which grow directly on the edges of its leaves. These tiny plants can be removed and attached elsewhere, allowing easy propagation and expansion of your aquascape.
