ADA Microsorum pteropus ‘Narrow Leaf’

Microsorum pteropus 'Narrow Leaf' is a refined variant of the classic Java Fern, valued by aquascapers for its elegant, elongated leaves and dependable hardiness. Native to Southeast Asia, this aquatic fern differs from rooted plants in that it grows attached to hardscape, such as driftwood or rocks, rather than being planted in substrate. The slender leaf shape sets it apart from the broader-leaved standard Java Fern, lending a more delicate and flowing aesthetic that’s particularly well-suited for jungle-style or natural aquascapes. Its slow growth and robust nature make it a favourite for both beginners and seasoned aquarists.

How to use in Aquarium

In aquariums, Microsorum 'Narrow Leaf' is a versatile addition, fitting nicely into midground or background spaces depending on the size of the tank. It is best attached to hard surfaces using aquarium-safe thread or glue, allowing its rhizome to naturally anchor over time. The plant’s soft, arching leaves create a gentle sense of movement in the water, making it a fantastic choice for low-flow or shrimp tanks where a more subtle visual is desired. It's equally at home in minimalist layouts or densely planted tanks, offering visual depth without overwhelming other plants or decor.

How to maintain Microsorum pteropus ‘Narrow Leaf’

This plant is very low-maintenance, making it ideal for aquarists of all skill levels. It prefers low to moderate lighting and does not tolerate strong, direct light well, which can lead to browning or algae issues. While Microsorum 'Narrow Leaf' doesn’t require CO₂ supplementation, it can benefit from it, especially in high-tech setups. Liquid fertilisers that feed the water column help support healthy growth, as nutrients are absorbed primarily through the leaves and rhizome rather than roots. Routine maintenance involves trimming away older or damaged leaves and ensuring the rhizome remains above the substrate to prevent rot. It thrives in a wide range of water parameters, with optimal conditions being temperatures between 20–28°C  and a pH between 6.0 and 7.5.

Emersed Growth

In addition to its submerged use, Microsorum pteropus 'Narrow Leaf' can also be grown emersed in high-humidity environments such as paludariums or terrariums. When grown above water, the leaves tend to become slightly thicker and more leathery. To transition from submerged to emersed growth, the water level should be lowered gradually to allow the plant to adapt. The rhizome should always remain moist, and high humidity must be maintained for successful emersed culture. This makes it a popular choice for aquascapers and terrarium keepers looking to blend aquatic and terrestrial plant forms in a seamless, jungle-like aesthetic.

Overall, Microsorum pteropus 'Narrow Leaf' is a beautiful, adaptable, and easy-to-care-for plant that adds depth and elegance to any aquatic or semi-aquatic setup. Its graceful form and hardy nature make it a staple in natural aquascaping and a reliable choice for nearly any tank environment.
