Microsorum pteropus/narrow leaf fern/Philippine fern (clump on steel mesh)

Description

Microsorum pteropus, commonly known as Java Fern, has several varieties, including the Narrow Leaf and Philippine Fern varieties. These aquatic plants are highly valued in the aquarium hobby for their unique appearances and ease of care. Here’s an overview and care guide for these varieties:

Key Features:

1. Narrow Leaf Java Fern:
   • Leaves: The Narrow Leaf variety has slender, elongated leaves that are narrower compared to the standard Java Fern. The leaves are typically dark green.
   • Growth Habit: Forms dense, bushy clumps and grows in a similar manner to other Java Fern varieties.
2. Philippine Fern:
   • Leaves: The Philippine Fern variety has more elongated and somewhat wavy leaves, giving it a distinct and elegant look. The leaves are also dark green.
   • Growth Habit: This variety can grow slightly taller than the standard Java Fern, making it suitable for midground and background planting in aquariums.

Care Tips:

1. Light: Both varieties thrive in low to moderate light conditions. High light can lead to algae growth on the leaves, so it’s best to avoid intense lighting.
2. Water Conditions:
   • pH: 6.0 – 7.5
   • Temperature: 68-82°F (20-28°C)
   • Hardness: Tolerant of a wide range of water hardness levels.
3. Substrate: Java Ferns should not be planted directly in the substrate. Instead, attach them to rocks, driftwood, or other decorations using fishing line, thread, or aquarium-safe glue until they anchor themselves.
4. Nutrients: They absorb nutrients from the water column. Using a liquid aquarium fertilizer can enhance growth, although CO2 supplementation is not necessary.
5. Water Flow: Moderate water flow is ideal. Avoid strong currents that can damage the delicate leaves or stagnant water which can promote algae growth.
6. Propagation: Propagates through rhizome division or by producing adventitious plantlets on the tips of mature leaves. These plantlets can be separated and attached to new surfaces.

Additional Tips:

• Compatibility: Both varieties are compatible with a wide range of fish and invertebrates. Their tough leaves make them less likely to be eaten by herbivorous fish.
• Maintenance: Regularly remove dead or decaying leaves to maintain water quality. Check for algae and clean the leaves if necessary.
• Positioning: Place Narrow Leaf Java Fern and Philippine Fern in the midground or background of the aquarium. They can create a natural, lush look when attached to driftwood or rocks.
