Java Fern ‘Windelov’ Care & Growing Tips
Microsorum pteropus ‘Windelov’ is a unique, attractive variant of Java Fern with finely branched, lacy leaf tips. It’s hardy, low-maintenance, and great for beginners.
1. Lighting Requirements
Low to Moderate Light (50-100 PAR is ideal).
Avoid intense lighting (may cause algae growth on leaves).
Can thrive under standard LED aquarium lights.
2. Water Parameters
Temperature: 68–82°F (20–28°C).
pH: 6.0–7.5 (tolerates slightly higher).
Hardness: Soft to moderately hard water (adaptable).
3. Planting & Substrate for Windelov
Do NOT bury the rhizome (thick horizontal stem)—it will rot.
Attach to driftwood, rocks, or decorations using:
Fishing line / cotton thread (temporary).
Super glue (cyanoacrylate, safe for aquariums).
Let roots naturally grip over time.
Can also be left floating until it attaches itself.
4. Fertilization & CO2
Not required but benefits from:
Liquid fertilizers like the Profito (low to moderate dosing).
Root tabs (if planted near substrate).
CO2 is unnecessary but can enhance growth.
5. Growth & Propagation
Slow-growing (patience needed).
Propagates via:
Rhizome division (cut with a sharp knife).
Plantlets (baby ferns grow on older leaves).
6. Common Issues & Fixes for Windelov
Black/Brown spots on leaves?
Normal (new growth forms from these).
If excessive, check for nutrient deficiencies (potassium helps).
Melting or holes in leaves?
Usually due to poor water conditions (check ammonia/nitrates).
Transition shock (if newly added).
Algae on leaves?
Reduce light duration (6–8 hours/day).
Add algae-eating shrimp (Amano, Nerite snails).
7. Tank Mates
Safe with:
Shrimp (Cherry, Amano).
Peaceful fish (Tetras, Bettas, Guppies, Corydoras).
Avoid:
Plant-nibblers (Goldfish, Cichlids).
Final Tips:
✔ Don’t rush growth—it’s naturally slow.
✔ Trim old leaves to encourage new growth.
✔ Stable water > high-tech care—it thrives on neglect!
With proper care, Java Fern ‘Windelov’ will grow into a beautiful, bushy centerpiece in your aquarium!
