Understanding Moneywort: A Closer Look
Moneywort (Hydrocotyle verticillata), also known as Water Pennywort, is an aquatic plant native to Asia and Europe. It is a fast-growing, submersed plant that thrives in a variety of aquarium conditions. Its round, green leaves, resembling miniature coins, create a dense carpet-like effect, adding visual interest and texture to the substrate.
Moneywort is a valuable addition to any aquarium ecosystem. It helps to absorb excess nutrients like nitrates and phosphates, contributing to the overall water quality. Its dense foliage provides hiding places and shelter for small fish and invertebrates, promoting a balanced and thriving community.
Types of Moneywort
While Hydrocotyle verticillata is the most common type of Moneywort cultivated in aquariums, there are other varieties, such as Hydrocotyle leucocephala and Hydrocotyle bonariensis, which can also be successfully grown in aquatic environments. Each variety may have slightly different growth habits and aesthetic characteristics, offering aquarists a range of choices to suit their preferences.
Setting the Stage: Ideal Conditions for Moneywort Growth
To ensure the optimal growth and flourishing of Moneywort in your aquarium, it’s essential to create an environment that closely mimics its natural habitat.
Water Parameters
- Temperature: 68-82°F (20-28°C)
- pH: 6.0-8.0
- Hardness: Soft to moderately hard (5-15 dGH)
Moneywort is relatively adaptable to a range of water parameters, making it suitable for various aquarium setups. However, maintaining these ideal conditions will promote healthy growth and vibrant foliage.
Lighting
Moneywort thrives in moderate to bright lighting conditions. Aim for 6-8 hours of light per day. While it can tolerate lower light levels, growth may be slower.
Substrate
Moneywort prefers a nutrient-rich substrate. A fine-grained sand or gravel substrate with a layer of nutrient-rich soil underneath will provide the necessary nutrients for optimal growth.

Preparing the Substrate
Before planting, gently loosen the substrate using your fingers or a small aquarium tool. This will create air pockets and allow the roots to penetrate easily.
Planting the Rhizomes
Moneywort is typically planted using its rhizomes, which are the horizontal stems that grow underground. Space the rhizomes about 2-3 inches apart. Gently bury the rhizomes in the substrate, ensuring that the nodes (small bumps along the rhizome) are covered.
Securing the Plant
To prevent the Moneywort from floating or shifting, you can use small rocks or aquarium weights to gently hold it in place.
Maintaining a Thriving Moneywort Carpet
Once planted, Moneywort requires regular maintenance to ensure its continued health and lush growth.
Fertilization
Moneywort benefits from regular fertilization. Use a balanced liquid fertilizer specifically designed for aquatic plants. Follow the manufacturer’s instructions for dosage and frequency.
Trimming and Pruning
As Moneywort grows, it may start to outgrow its designated space. Regular trimming and pruning will help to maintain its shape and prevent overcrowding.
Use sharp scissors or pruning shears to trim the stems to the desired length. You can also remove any dead or decaying leaves to promote healthy growth.
Water Changes
Regular water changes are essential for maintaining good water quality and preventing the buildup of harmful substances. Perform partial water changes of 25-50% every 1-2 weeks. (See Also: How to Get to Sea Aquarium Sentosa? – Easy Guide Inside)
Troubleshooting Common Moneywort Problems
While Moneywort is generally a hardy plant, it can sometimes encounter problems.
Algae Growth
Excess algae growth can compete with Moneywort for nutrients and light. To control algae, ensure proper lighting, fertilization, and water changes. Consider introducing algae-eating fish or invertebrates to your aquarium.
Melting Leaves
Melting leaves can indicate a sudden change in water parameters, such as temperature or pH. Adjust the water conditions gradually to prevent stress on the plant.
Yellowing Leaves
Yellowing leaves can be a sign of nutrient deficiency. Increase fertilization or consider using a specialized fertilizer for Moneywort.
How to Propagate Moneywort
Moneywort is easy to propagate, allowing you to expand your aquatic plant collection.
Stem Cuttings
Take a healthy stem cutting, about 4-6 inches long, and remove the lower leaves. Plant the cutting in the substrate, ensuring that the nodes are covered.
Division
If you have a well-established Moneywort plant, you can divide it by carefully separating the rhizomes. Each section should have several nodes and healthy leaves. Plant the divisions in the substrate, as described above.
