High lighting is strongly recommended.
Intense light enhances the plant's attractive pink, orange, red, and cream variegation.
Under low light, coloration fades and growth becomes weak.
CO₂ supplementation is essential for optimal growth.

Iron supplementation supports richer red and pink coloration.
Stable nutrient levels are important due to its slow growth and variegated nature.

Commonly used as a highlight or focal plant.
Its unique coloration creates strong contrast against green aquatic plants.
Propagated through stem cuttings.
Cut healthy stems and replant them into the substrate.
Growth is relatively slow, so propagation takes longer than many stem plants.
Maintain stable CO₂, lighting, and nutrient levels.
Avoid frequent relocation, as the plant may take time to re-establish.
Plant in small groups to create an eye-catching accent.
Good water circulation helps prevent algae on the slow-growing leaves.
