Here’s all about Java Fern (Microsorum pteropus), a popular and hardy aquatic plant often used in freshwater aquariums:
Scientific Name: Microsorum pteropus
Common Name: Java Fern
Origin: Southeast Asia (Malaysia, Thailand, Indonesia)
Plant Type: Rhizome-based, epiphytic (grows attached to surfaces)
Growth Style: Slow-growing, rhizome plant that sends out long, narrow, green leaves.
Attachment: Best grown attached to driftwood, rocks, or decor (not buried in substrate).
Leaf Types: Comes in several variations:
Standard Java Fern
Windelov Java Fern (frilly leaf tips)
Narrow Leaf Java Fern
Trident Java Fern (forked leaf tips)
Needle Leaf Java Fern
| Parameter | Value |
|---|---|
| Tank Size | 10 gallons and up |
| Lighting | Low to moderate |
| Temperature | 20–28°C (68–82°F) |
| pH Range | 6.0–7.5 |
| Hardness | Soft to moderately hard water |
| CO₂ | Not required (but beneficial) |
| Fertilizer | Not mandatory; liquid ferts help growth |
By Rhizome Division: Cut and reattach pieces of the rhizome.
By Adventitious Plantlets: Small plantlets grow on mature leaves and can be separated when large enough.
Attach to Hardscape: Use thread, fishing line, or super glue gel.
Avoid Substrate Burial: Burying the rhizome causes rot.
Best Used: Midground or background, depending on variety and tank size.
Fish Safe: Great with most community fish.
Ideal for: Cichlids, goldfish, bettas, shrimp (leaves provide shelter).
Not eaten easily: Tough leaves deter herbivorous fish.
Don’t bury the rhizome.
Clean algae off leaves gently.
Remove decaying leaves to promote healthy new growth.
Low maintenance – perfect for beginners.
