Java Fern, Microsorum pteropus, is one of the most iconic and widely grown aquarium plants in the hobby, native to the tropical rivers and streams of Southeast Asia and prized for its broad, lance-shaped, deep green fronds that bring a bold, lush presence to any planted aquascape. Exceptionally hardy and adaptable, it thrives in a wide range of water conditions with no CO2 or substrate planting required — simply attach it to driftwood or rocks and watch it flourish. Its slow, steady growth and near-indestructible nature make it the perfect choice for beginners and a reliable staple for experienced aquarists alike.Propagation: Propagates naturally by producing daughter plantlets along the edges and tips of mature fronds.
