Water Parameters:

1. Temperature: Keep the water temperature in the range of 22-28°C (71.6-82.4°F).
2. pH Level: Maintain a slightly acidic to neutral pH level, ideally between 6.0 to 7.5.
3. Water Hardness (dH): Hygrophila Lancea 'Araguaia' can adapt to a wide range of water hardness, but prefers soft to moderately hard water with a dH range of 2-15.
4. Lighting: Provide moderate to high-intensity lighting for at least 8-10 hours per day. LED lights are recommended for energy efficiency and plant growth.
5. Substrate: Use a nutrient-rich substrate to promote healthy growth. A mixture of gravel and laterite or specialized aquatic plant substrate works well.
6. CO2 Injection: CO2 supplementation can enhance growth, but Hygrophila Lancea 'Araguaia' can thrive without it. Aim for a CO2 level of 10-30 ppm if supplementing.
7. Nutrient Supplementation: Regular fertilization with liquid or substrate fertilisers containing essential nutrients like nitrogen, phosphorus, and potassium is beneficial.
8. Water Circulation: Ensure good water circulation to distribute nutrients and prevent stagnant areas.
9. Maintenance: Trim the plant regularly to promote bushy growth and remove any decaying leaves. Prune runners to control spreading if necessary.

By maintaining these water parameters and providing proper care, you can cultivate healthy and vibrant Hygrophila Lancea 'Araguaia' in your aquarium.
