(154) Rotala indica

The aquatic plant sold as Rotala indica is frequently a misidentified variant of Rotala rotundifolia. This is a common confusion in the aquarium hobby. The true Rotala indica is less common, but the two can be distinguished by their growth habits.

• Lighting: Moderate to high-intensity lighting is necessary to bring out the red or pink color in both species.
• CO2 Injection: While not strictly required, adding CO2 significantly boosts growth and color intensity.
• Fertilization: A regular supply of nutrients, particularly iron, is important. A rich substrate will also help, especially for the true Rotala indica.
• Propagation: Both are easy to propagate by replanting trimmed stems.
• Maintenance: Regular trimming is necessary to maintain a dense, bushy appearance. Untrimmed stems will reach for the surface, causing lower leaves to be shaded and fall off. 

• Rotala rotundifolia 'Green': A green variant that is easy to grow.
• Rotala rotundifolia 'H'ra': A type known for its intense orange and red color.
• Rotala rotundifolia 'Orange Juice': A new cultivar that shows orange-pink coloration.
