Rotala

Rotala, specifically Rotala rotundifolia, is a versatile aquarium plant known for its adaptability and distinctive appearance. This plant exhibits two different leaf forms depending on its growth conditions: emersed leaves are rounded, while submerged leaves are narrow and lanceolate. The coloration of Rotala can vary significantly with light and environmental conditions, often turning a rich wine red under strong lighting. It also features pale pink flowers, which can be observed when grown in shallow, emersed conditions.

Rotala rotundifolia is a popular choice among aquarists due to its relatively low maintenance needs. It thrives in a range of lighting conditions but requires adequate light to prevent the loss of its lower leaves, which is a common sign of insufficient light. The plant is tolerant of cooler temperatures and can be grown emersed in shallow water, where it may flower. Propagation is straightforward through cuttings, making it an accessible option for both beginners and experienced aquarists. This plant grows at a medium rate and can reach heights of 15 to 30 centimeters or more. It is well-suited for a variety of aquarium setups, benefiting from low to moderate CO2 levels.
