Microsorum Pteropus - Windelov

Microsorum Pteropus 'Windelov' (Windelov Java Fern)

Microsorum Pteropus 'Windelov', commonly known as Windelov Java Fern, is one of the most distinctive and elegant varieties of Java Fern available in the aquarium hobby. Renowned for its finely branched, lace-like leaf tips, this beautiful aquatic plant adds exceptional texture and visual interest to planted aquariums.

Originally developed from the standard Java Fern, Windelov retains the same hardy and beginner-friendly nature while offering a more decorative appearance. Its adaptability, slow growth rate, and minimal care requirements make it a favorite among aquascapers, shrimp keepers, and planted tank enthusiasts. Due to its unique foliage, it is often used as a focal point in natural aquascapes and nature-style aquariums.

Appearance

The most distinctive feature of Microsorum Pteropus 'Windelov' is its bright green leaves that split repeatedly at the tips, creating an intricate lace or antler-like appearance. The leaves grow from a creeping rhizome and can reach 15–25 cm in height under ideal conditions.

Its delicate-looking foliage creates a soft, elegant effect in the aquarium while remaining surprisingly durable and long-lasting.

Windelov Java Fern adapts well to a wide range of aquarium conditions and remains healthy in both community and species-specific setups.

Lighting

Low to medium lighting is ideal. Strong lighting is not necessary and may encourage algae growth on the leaves. Under stable lighting conditions, the plant develops dense and healthy foliage.

CO₂ and Fertilization

This plant thrives without CO₂ injection, making it an excellent choice for low-maintenance aquariums. While not required, liquid fertilizers can promote slightly faster growth and richer coloration.

Planting and Placement

Like all Java Fern varieties, the rhizome should never be buried in the substrate. Doing so can cause the plant to rot and die.

Instead, attach the plant to:

Driftwood

Lava rock

Natural stone

Aquarium decorations

The roots will gradually anchor themselves to the surface over time.

Recommended Placement

Midground
