Don’t bury the rhizome! Attach it to hardscape like:
Driftwood
Lava rocks
Aquarium ornaments
Use thread, fishing line, or super glue gel to fix it in place.
Over time, the roots will naturally grip the surface.
Adventitious Plantlets: Tiny new plants appear on older leaves.
Rhizome Division: Cut a portion of the rhizome with several leaves and roots.
Great for: Nano tanks, shrimp tanks, nature-style aquascapes
Safe with: Goldfish, bettas, cichlids, community fish
Use in Aquascaping: Midground or foreground for nano tanks; tied to small wood pieces or stones for layering
Clean algae gently with a soft brush.
Trim dead or old leaves near the base.
Don’t overexpose to strong light – can lead to algae issues.
Liquid fertilizers boost growth, especially potassium and micronutrients.
| Problem | Cause |
|---|---|
| Leaf browning | Aging leaves or poor nutrients |
| Rhizome rot | Buried in substrate |
| Algae on leaves | High light, poor water flow |
| Stunted growth | Low nutrients, cold temps |
✅ Perfect for nano tanks and fine-detail scaping
✅ Hardy and beginner-friendly
✅ Doesn't need substrate
✅ Grows in low-light conditions
✅ Beautiful, refined leaf shape for a delicate look
