Java Fern
Microsorum pteropus
Family: Polypodiaceae
📍 Southeast Asia
Java fern is one of the most forgiving aquatic plants, thriving under low light without CO2 injection. It must be attached to hardscape rather than planted in substrate, as burying the rhizome will cause it to rot. New plantlets emerge from the edges of mature leaves, making propagation effortless.
