Bacopa monnieri, also known as water hyssop or brahmi, is a popular aquatic plant in the aquarium hobby and also has significant medicinal uses in traditional medicine practices like Ayurveda. Here are some key points about Bacopa monnieri:

1. Appearance: Bacopa monnieri has small, bright green leaves that grow in pairs along its stems. It can grow both submerged and emersed, and in aquariums, it often grows vertically, creating a bushy appearance.

2. Lighting: This plant can thrive in a wide range of lighting conditions, from low to high light. Higher light levels will promote compact growth and more intense green coloration.

3. Water Conditions: Bacopa monnieri prefers slightly acidic to neutral pH levels (around 6.0-7.5) and temperatures between 64-82°F (18-28°C). It is adaptable to various water hardness levels.

4. Substrate: It can be planted in nutrient-rich substrates, but it can also grow well in plain gravel or sand. Providing root tabs or liquid fertilizers can help promote healthy growth.

5. CO₂ and Nutrients: While CO₂ supplementation can enhance growth, Bacopa monnieri can thrive without it. Regular fertilization with a balanced liquid fertilizer will help maintain its health and vibrant appearance.

6. Propagation: Propagation is easy through stem cuttings. Simply cut a healthy stem and replant it into the substrate. It will develop roots and continue to grow.

7. Placement: Bacopa monnieri is versatile and can be used in various parts of the aquarium. It can be planted in the background or along the sides to create a natural-looking backdrop.

8. Compatibility: It is compatible with most freshwater fish and invertebrates. Its dense growth provides cover and shelter for aquarium inhabitants.

9. Medicinal Uses: Outside of aquariums, Bacopa monnieri is used in traditional medicine for its cognitive-enhancing properties and is considered an adaptogen.
