(153) Microsorum pteropus 'Narrow Leaf'

Microsorum pteropus 'Narrow Leaf', commonly known as Narrow Leaf Java Fern, is a variant of the classic Java fern distinguished by its elongated, slender leaves. It is a highly popular and easy-to-care-for plant, making it an excellent choice for beginner aquarists

• Epiphytic growth: Like other Java ferns, it should not be buried in the substrate. The rhizome must be attached to a hard surface like driftwood, rocks, or other decor, using thread, fishing line, or aquarium-safe super glue.
• Lighting: It is highly adaptable and thrives in low to moderate lighting. Too much light can cause the leaves to burn or encourage unwanted algae growth.
• Water parameters: This plant is very forgiving and can tolerate a wide range of water conditions.
  • Temperature: 68–82°F (20–28°C).
  • pH: 5.5–8.0.
• Fertilization: It absorbs nutrients directly from the water column. While it will survive without additional fertilizers, regular liquid fertilization, especially with potassium and iron, can promote healthier, more vigorous growth and prevent deficiencies.
• Placement: The Narrow Leaf Java Fern is versatile and can be placed in the midground or background of the aquarium, depending on the tank size and desired effect. 

• Rhizome division: The most common method is to cut the horizontal rhizome into smaller pieces, each with a few leaves, and attach the new sections to hardscape.
• Plantlets: New, miniature plantlets will naturally develop on the edges of mature leaves. Once they have developed roots, you can gently detach them and reattach them elsewhere in the tank. 

• Rhizome rot: Burying the rhizome is the most common mistake and will cause the plant to rot.
• Nutrient deficiency: Yellowing leaves or brown patches can indicate a lack of potassium or other nutrients.
• Java fern melt: This refers to the browning and eventual disintegration of the leaves. It can be caused by drastic changes in water parameters, incorrect planting, or nutrient deficiency.
