Rotala rotundifolia (Rotala)

Cultivation Requirements

This plant thrives in well-lit aquariums with consistent CO2 supplementation. Higher light intensity encourages a more compact growth habit and richer red coloration in the shoot tips. It prefers soft to medium-hard water and a nutrient-rich substrate, although it can also absorb nutrients directly from the water column.

Maintenance and Pruning

Rotala rotundifolia is a fast grower that requires regular pruning to maintain its shape and prevent the lower portions of the stems from becoming shaded and losing leaves. Trimming the tops encourages branching, resulting in a denser, bushier appearance. The cuttings can be easily replanted into the substrate to propagate the plant.

Taxonomic Note

There is frequent confusion in the aquarium trade between Rotala rotundifolia and the true Rotala indica. Many plants sold as Rotala indica are actually forms of Rotala rotundifolia. This identification is made with moderate confidence based on standard commercial availability and typical morphology observed in aquarium cultivation.
