Description
Japanese Pennywort (Hydrocotyle tripartita “Japan”) is a fast-growing, low-maintenance aquarium plant that can be used as a carpet or foreground plant, or allowed to grow bushier. It thrives in a range of conditions, including without CO2 injection, although CO2 and supplemental fertilization will promote faster, denser growth.Â
Here’s a more detailed guide to caring for Japanese Pennywort in an aquarium:Â
1. Planting and Placement:
-
Substrate:Plant in fine-grained substrate, preferably one that is nutrient-rich, or you can allow it to float at the surface.Â
-
Placement:Can be used as a foreground plant, or allowed to grow upright for a more bushy appearance.Â
-
Propagating:You can propagate by trimming stems and replanting, or by splitting apart dense clumps and replanting the roots.Â
2. Light:
- Medium to High Light:Â It prefers medium to high light levels.Â
- Low Light:Â Can grow in lower light, but growth will be slower and it might not be as dense.Â
3. Water Parameters:
- pH:Â Thrives in slightly acidic to neutral water (pH 6.0-7.5).
- Temperature: Ideal temperature range is 68-82°F (20-28°C).
- Flow:Â Requires moderate water flow to prevent debris buildup and promote nutrient absorption.Â
4. Fertilization and CO2:
- CO2:Â While it can grow without CO2, supplementation will promote faster, denser growth.
- Fertilizers:Â Regular all-round fertilization is crucial for healthy, lush growth.Â
5. Maintenance:
- Trimming:Â Trim frequently, especially if used as a carpet, to maintain a low, dense growth pattern.Â
- Removing Runners:Â If you don’t want the plant to spread, cut any runners that appear.Â
6. Additional Tips:
- Clean and cycled tank:Â Ensure your tank is clean and cycled with suitable water parameters.Â
- Aquascaping:Â Can be used as a foreground plant or to create a dense, low-growing carpet.Â
