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.
