Microsorum pteropus ‘Narrow’, also known as Narrow Leaf Java Fern, is a popular aquarium fern valued for its long, slender fronds and easy care requirements. This epiphytic plant is a variant of the classic Java Fern, with tighter and narrower leaf blades that offer vertical motion and gentle texture in midground-background layout zones. Its deep green foliage provides calming contrast and visual structure, making it a staple in both beginner and advanced aquascapes.

This plant grows best in low-medium lighting conditions (6–8 hrs/day) and does not require nutrient-rich substrate. Instead, it thrives when attached-aquarium hardscape such as driftwood or porous stone. CO₂ is optional, though a mild injection can support slightly faster growth and deeper green tones. The rhizome should never be buried in substrate—attach using fishing line, thread, or aquarium-safe glue-secure it-surfaces.

Microsorum ‘Narrow’ grows slowly-moderately, with new fronds emerging from the rhizome over time. It can be propagated by cutting and replanting rhizome sections that have healthy leaves and roots. This Java Fern variety is ideal for low-maintenance tanks, community tanks, and shrimp environments where its tough leaves resist nibbling and algae buildup. Use it in flowing groups or as an accent along wood-simulate natural stream margins or riverbanks.
