Hygrophila sp. “Chai”  is a rare, slow-growing variegated stem plant. Originating as a mutation of Hygrophila lancea “Araguaia”, it is prized for its striking pastel-to-intense pink leaf margins and green central veins. It requires advanced, high-tech aquarium conditions to thrive.

Appearance and Growth Habit:

• Features narrow, linear, curved leaves with green centers and white-to-pink variegation.
• Displays a low-growing, creeping, or prostrate habit that hugs the substrate under strong illumination.
• Grows extremely slowly compared to standard aquarium stem plants.

Optimal Care Requirements:

• Lighting: High light intensity is necessary to maintain its compact form and vibrant pink coloration.
• CO2 and Flow: Requires strong, stable CO2 injection (40–50 ppm) paired with good water circulation and gas exchange.
• Water Parameters: Prefers a neutral-to-slightly acidic pH (6.5–7.5) in clean, biologically stable, mature aquariums.
• Maintenance: Highly sensitive to algae due to its slow growth rate. Keep surrounding areas clear of faster-growing plants that can crowd or shade it out.
