Hygrophila lancea 'Chai' is an intriguing aquatic plant known for its distinctive appearance and ease of care. As a tissue culture plant, it arrives free from pests and diseases, ensuring a clean start for your aquarium setup. Here’s a detailed overview:

Description

• Appearance: Hygrophila lancea 'Chai' features elongated, lance-shaped leaves that are typically a rich green color. The plant has a bushy and upright growth habit, with leaves that can have a slight reddish tint under high light conditions. The plant’s texture and form add a dynamic visual element to aquascapes.
• Size: It generally grows to about 15-30 cm (6-12 inches) in height. Its height and bushy growth make it suitable for the midground or background of aquariums, where it can serve as a focal point or backdrop.

Habitat

• Native Range: Hygrophila lancea is native to Southeast Asia, including regions of Thailand and Malaysia. The 'Chai' variant is a cultivated form that has been selectively bred for its unique characteristics.
• Natural Habitat: In the wild, Hygrophila lancea grows in slow-moving waters, typically in shaded or partially shaded environments. It thrives in nutrient-rich substrates and can adapt to a variety of aquatic conditions.

Care and Maintenance in Aquariums

• Tank Size: Due to its potential height, Hygrophila lancea 'Chai' is best suited for medium to large aquariums. It can be used in the midground or background to create a lush, textured backdrop.
• Water Parameters: The plant thrives in tropical water conditions with temperatures ranging from 22-28°C (72-82°F) and a pH level between 6.0 and 7.5. It prefers soft to moderately hard water but can adapt to a range of water conditions.
• Substrate: A nutrient-rich substrate is recommended to support healthy growth and vibrant coloration. Aquasoils or other substrates designed for planted tanks are ideal.
• Tank Setup: Hygrophila lancea 'Chai' does well in moderate to high lighting conditions. Under higher light, the plant may exhibit more vibrant colors, including reddish tints. CO2 supplementation is beneficial for promoting lush growth and enhancing coloration, though the plant can tolerate lower-tech setups. Regular dosing with liquid fertilizers will help maintain the plant’s health and appearance.

Growth and Maintenance

• Growth Rate: Hygrophila lancea 'Chai' has a moderate growth rate. It will gradually develop into a dense and bushy plant, adding visual interest to the aquarium.
• Propagation: Propagation is typically done by trimming and replanting the plant’s stems. New shoots will emerge from the base, which can be separated and replanted to spread the plant further across the tank.
• Maintenance: Regular trimming is necessary to maintain the plant’s shape and prevent it from becoming leggy. Removing older or damaged leaves will help keep the plant healthy and prevent algae buildup.

Challenges

• Light and CO2 Requirements: While Hygrophila lancea 'Chai' can tolerate a range of light conditions, it performs best with moderate to high lighting. In lower light conditions, its growth may become elongated and less vibrant. CO2 supplementation enhances growth and color but is not strictly necessary in low-tech setups.
• Algae Growth: Due to its moderate growth rate, this plant can be prone to algae on its leaves if not properly maintained. Keeping light levels moderate and ensuring good water quality will help prevent this issue.
