Stoffels Microsorum pteropus

The Microsorum pteropus, commonly known as Java Fern, is a classic and widely popular aquatic plant that is well-known for its attractive, long, and wavy green leaves. Native to Southeast Asia, this hardy plant is suitable for both beginners and advanced aquarists, as it thrives in a wide variety of conditions. Its versatility allows it to be used as a midground or background plant, often attached to driftwood or rocks. The Java Fern’s slow to moderate growth rate, unique texture, and ease of care make it a fantastic choice for creating a natural, lush look in aquascapes.

Key Features:

• Large, Wavy Green Leaves: Java Fern has elongated, vibrant green leaves with a slightly wavy texture, adding a natural and flowing aesthetic to the aquarium.
• Versatile Planting Options: The rhizomes can be easily attached to hardscape elements such as driftwood or rocks, giving aquarists flexibility in aquascape design.
• Slow to Moderate Growth Rate: Java Fern grows slowly to moderately, requiring little maintenance, which makes it ideal for those looking for a low-effort plant.
• Hardy and Easy to Care For: Java Fern is highly adaptable and can thrive in a variety of conditions, from low to medium light, making it suitable for all aquarists.

Care Requirements:

• Lighting: Java Fern requires low to medium lighting to thrive. It grows well even under low-light conditions, making it an excellent choice for low-tech aquariums. Too much light can lead to algae growth on its leaves.
• CO2: CO2 supplementation is not necessary for Java Fern. It can thrive in low-tech tanks without CO2, though adding CO2 can slightly enhance its growth rate.
• Water Parameters: Java Fern is highly adaptable to different water conditions and grows well in a pH range of 6.0-7.5, with temperatures between 20-28°C. It is not picky about hardness and can tolerate soft to moderately hard water.
• Trimming: Due to its slow growth rate, Java Fern requires minimal trimming. Remove older or damaged leaves to maintain a healthy appearance.

Planting Tips:

• Attach to Hardscape: Java Fern should not be buried in the substrate, as this can cause the rhizome to rot. Instead, attach the plant to hardscape elements such as rocks or driftwood using thread or aquarium-safe glue until it anchors itself.
• Avoid Burying the Rhizome: Ensure the rhizome remains above the substrate to prevent rot. The roots can grow into the substrate, but the rhizome should always be kept uncovered.
• Propagation: Java Fern propagates through rhizome division or by producing adventitious plantlets on older leaves. To propagate, simply cut a section of the rhizome with leaves attached and reattach it to a new location.
