Rotala rotundifolia 'Red' is a stunning variant of the classic Rotala rotundifolia, known for its vibrant red and pink hues. This aquatic plant is a favorite among aquarium hobbyists who aim to add a splash of color to their freshwater tanks. Its striking appearance and relatively easy care requirements make it a popular choice for both novice and experienced aquarists. Here's a closer look at Rotala rotundifolia 'Red':


  • Appearance: This variant boasts slender, pointed leaves that grow in an alternating pattern along its stems. Under high light conditions, the leaves and stems can develop intense red and pink colors. The contrast between its fine texture and vivid coloration can add visual interest and depth to an aquarium.
  • Growth Habit: Rotala rotundifolia 'Red' has a fast growth rate and tends to grow upwards towards the light. It can be encouraged to branch out and become bushier with regular pruning, which is beneficial for aquascaping purposes.

Care Requirements:

  • Lighting: High lighting is crucial for Rotala rotundifolia 'Red' to achieve its best coloration. Under lower light, the plant may grow more greenish or pale.
  • CO2 Supplementation: Adding CO2 to the aquarium can significantly enhance the growth rate and color intensity of this plant. While it can grow without CO2, the addition of CO2 will yield better results.
  • Nutrients: Regular dosing of both macro and micronutrients is important to support its rapid growth and vibrant color. Iron is particularly beneficial for promoting the red pigmentation.
  • Water Conditions: It prefers water temperatures between 22°C and 28°C (72°F to 82°F), with a pH of 5.5 to 7.5. Like many aquatic plants, it thrives in stable water conditions with good quality.


Propagation of Rotala rotundifolia 'Red' is straightforward and similar to other stem plants. Simply cut a portion of the stem from the top and replant it in the substrate. This method allows aquarists to manage the height of the plants and fill in areas of their aquascape with new growth.

Aquascaping Uses:

  • Background and Midground: Depending on the tank size, Rotala rotundifolia 'Red' can be used effectively in both the background and midground areas of an aquarium. Its vertical growth and vibrant coloration make it an excellent choice for adding depth and contrast.
  • Group Plantings: Planting it in groups or dense clusters can create a stunning visual effect, with the reds and pinks standing out against the greens of other plants.


While Rotala rotundifolia 'Red' is considered relatively easy to grow, achieving the most vibrant red colors requires optimal conditions, including high light and CO2 supplementation. Without these, the plant may not reach its full color potential.

Rotala rotundifolia 'Red' is an excellent choice for aquarists looking to introduce color and texture into their planted tanks. Its care requirements are manageable for most, and with the right conditions, it can become a captivating focal point in the aquarium.
