Rotala rotundifolia – Red-Green Aquarium Stem Plant
Rotala rotundifolia is a popular freshwater aquarium stem plant loved by aquascapers for its fast growth, soft texture, and beautiful color variation. In lower lighting, this plant typically stays bright green, while stronger lighting, steady nutrients, and optional CO2 can bring out pink to red tones.
This versatile stem plant works well in both midground and background placements. With regular trimming, Rotala rotundifolia can form dense, bushy clusters that add movement, color, and natural texture to planted aquariums, shrimp tanks, and peaceful community setups.

Tank Placement
Rotala rotundifolia works well as a midground highlight or background plant in freshwater planted aquariums. Plant stems in small groups with a little space between each stem so light can reach the lower leaves and encourage fuller growth.
Its fine leaves and colorful growth look especially attractive near bright green plants, carpeting plants, driftwood, or natural stone. When planted in groups and trimmed regularly, Rotala rotundifolia can create a soft, bushy background with beautiful green, pink, and red tones.
Lighting, CO2 & Nutrients
Rotala rotundifolia grows best with medium to high lighting. In lower-light aquariums, it usually stays greener. Under stronger light, it can develop brighter pink to red coloration and more compact growth.
CO2 is not always required, but it is recommended for denser growth, faster development, and stronger coloration. This plant also benefits from steady liquid fertilization and a nutrient-rich substrate to support fast, healthy growth.
Trimming & Propagation
Trim Rotala rotundifolia regularly to maintain shape and encourage bushier, more compact growth. Healthy stem tops can be replanted directly into the substrate to create fuller clusters or expand the plant into other areas of the aquarium.
Because this plant grows quickly, regular trimming helps prevent shading and keeps lower leaves healthier. Replanting cuttings is an easy way to create a dense, colorful background or midground group.
