Java fern (Microsorum pteropus)

Java fern is a hardy, low-maintenance aquatic plant ideal for freshwater and planted aquariums. Its distinctive feathery green fronds create natural texture and provide shelter for fish and invertebrates. This slow-growing plant thrives in low to moderate light and does not require CO₂ supplementation, making it perfect for beginners and established tanks alike. Java fern attaches naturally to rocks, driftwood, and hardscape—simply tie it with fishing line until roots establish. It prefers cooler water temperatures and benefits from gentle water flow. Rich in nutrients and naturally pest-resistant, Java fern helps reduce algae while adding visual depth to any aquascape. A versatile choice for nano tanks, community setups, and reef refugiums.
