Hygrophila polysperma, commonly known as Indian Waterweed, Dwarf Hygrophila, or Sunset Hygro, is a popular and adaptable aquatic plant in the aquarium hobby. Native to Southeast Asia, it has become widely distributed and cultivated in the aquarium trade due to its ease of care and attractive appearance. Here are key details about Hygrophila polysperma:

  1. Appearance:

    • Leaves: The leaves of Hygrophila polysperma are typically lanceolate (lance-shaped) and can vary in color based on environmental conditions. Under high light, the leaves may exhibit shades of green, red, or even pink.
    • Stem: It has a slender and branching stem, allowing it to form dense clusters in the aquarium.
  2. Growth Habit:

    • Hygrophila polysperma is known for its fast growth, making it an excellent choice for beginners. It can quickly fill in an aquarium, providing a lush and vibrant look.
    • The plant has a bushy and upright growth habit, and regular pruning is often required to control its size and shape.
  3. Lighting:

    • This species is adaptable to a wide range of lighting conditions but tends to display more intense colors under high light.
    • It can thrive in moderate to high lighting but can also tolerate lower light levels.
  4. Water Parameters:

    • Temperature: 68-82°F (20-28°C)
    • pH: 6.0-7.5
    • Hardness: Soft to moderately hard water is generally suitable.
  5. Substrate and Planting:

    • Hygrophila polysperma can be planted in the substrate. Provide a nutrient-rich substrate to support its growth, and planting in groups can enhance its visual impact.
    • The plant can also be floated in the water, and it may develop roots from the nodes.
  6. Propagation:

    • Propagation is straightforward and can be achieved by cutting and replanting stem cuttings. The cuttings can be planted directly into the substrate.
    • The plant can also propagate by producing lateral shoots.
  7. Compatibility:

    • Hygrophila polysperma is generally compatible with a variety of aquarium fish and other aquatic plants.
    • It can be used in both freshwater and brackish water setups.

    • Trim the tops of the stems to encourage lateral growth and maintain a bushy appearance.

While Hygrophila polysperma is popular for its vibrant colors and ease of care, it's important to note that in some regions, it is considered an invasive species due to its ability to grow rapidly and form dense populations in natural water bodies. Therefore, it's crucial to dispose of excess or unwanted plants responsibly and avoid introducing them into local ecosystems where they may become invasive.
