Java Fern 'Microsorum pteropus' Narrow

Java Fern Microsorum pteropus 'Narrow' is a fascinating cultivar of the classic Java Fern, Microsorum pteropus. As the name suggests, 'Narrow' has slimmer, more elongated leaves compared to the traditional Java Fern, giving it a more delicate and elegant look. This variety is especially favored for aquascaping due to its unique appearance and versatility in various tank setups.

Care Tips for Java Fern 'Narrow':

1. Light Requirements:

   • Like the standard Java Fern, 'Narrow' thrives in low to moderate light. It can tolerate low-light conditions, making it an excellent plant for low-tech aquariums. However, moderate light can help it grow a bit faster and develop richer green coloration, though you should avoid very intense light, as that can promote algae growth on the leaves.

2. Water Parameters:

   • Temperature: 'Narrow' prefers 72–82°F (22–28°C), which is ideal for most tropical fish and invertebrates.
   • pH: It does best in slightly acidic to neutral water, with a pH range of about 6.0–7.5.
   • Hardness: Java Fern 'Narrow' is adaptable to both soft and moderately hard water, just like the standard variety.

3. Substrate:

   • No substrate planting required! Java Fern 'Narrow' should be attached to rocks, driftwood, or decorations. You can use super glue gel or fishing line to secure it in place. As with other Java Fern varieties, the rhizome should never be buried in the substrate, as this can cause rot.

4. Growth Rate:

   • Like the regular Java Fern, 'Narrow' grows at a moderate rate, meaning it won’t outgrow your tank too quickly. It forms a bushy appearance over time and can eventually spread across surfaces.

5. Pruning:

   • Java Fern 'Narrow' is easy to maintain and doesn’t require much pruning. However, you can trim dead or yellowing leaves to keep it looking fresh. When pruning, always be careful not to cut into the rhizome, as that could damage the plant.

6. Fertilization:

   • While 'Narrow' can benefit from light fertilization, it doesn’t require heavy feeding. Use a balanced liquid fertilizer sparingly to promote healthy growth. Over-fertilizing can lead to algae growth, so it’s best to feed modestly.

7. Positioning in the Tank:

   • Due to its slender leaves, 'Narrow' is well-suited for midground placement in aquariums. It works well in aquascapes where you want to add texture and depth, as its narrower leaves contrast nicely with broader-leaved plants.

Interesting Facts:

1. Unique Leaf Shape:

   • The most distinctive feature of 'Narrow' is its long, narrow leaves, which give it a much more elegant and refined appearance compared to the standard Java Fern. The leaves often have a slightly wavy or ruffled edge, adding to its visual appeal.

2. Hardy and Low-Maintenance:

   • Like the classic Java Fern, 'Narrow' is incredibly hardy and low-maintenance. It can thrive in a wide range of water parameters, light levels, and temperatures, making it suitable for almost any aquarium setup.

3. Slow to Moderate Growth:

   • Java Fern 'Narrow' grows at a moderate pace, so it won’t need frequent trimming. Its slow growth rate is ideal for aquariums that don’t require constant plant maintenance.

4. Great for Aquascaping:

   • The unique, narrow leaves of 'Narrow' make it a favorite among aquascapers. It pairs beautifully with other plants, especially those with wider, bushier leaves, and can help create a contrast in textures and forms within an aquascape.

5. Perfect for Shrimp Tanks:

   • Like other Java Fern varieties, 'Narrow' is a great plant for shrimp tanks. Its dense, bushy structure provides hiding spots for shrimp and other small invertebrates, and the leaves are also great for them to graze on.

Fun Fact:

• Microsorum pteropus 'Narrow' is a natural mutation of the regular Java Fern, where it was selectively bred for its narrower leaf form. While it has similar care requirements to the regular variety, its unique look makes it stand out in an aquascape.
