• Height: 20–50 cm (8–20 inches)
• Growth Rate: Fast
• Color: Green to shades of pink, orange, or red
• Difficulty: Intermediate

Why Choose Rotala Rotundifolia for Your Aquascape?

This plant is perfect for intermediate aquascapers who want to:

• Add dynamic contrast and movement to planted tanks
• Experiment with stem plant trimming techniques and bushy plantings
• Highlight color transformations via lighting and nutrients
• Create impressive, dense background or midground sections


Rotala rotundifolia thrives when provided with the proper care, transforming an average tank into an aquatic showpiece. Once you master its requirements, you can unlock endless design possibilities.

Rotala Rotundifolia Care Requirements

Tank Setup & Placement

• Tank Size: 10 gallons (38 liters) or larger recommended
• Placement: Midground to background
• Companions: Compatible with most community fish and shrimp species

For the best visual impact, plant Rotala rotundifolia in dense groups, allowing enough space for stems to spread and fill in. Combine with contrasting leaf shapes like Java fern or carpeting plants for a multi-layered effect.

Lighting Requirements

Lighting plays a vital role in this plant’s health and color:

• Light Intensity: Medium to high (30–50 PAR)
• Photoperiod: 8–10 hours/day

Higher lighting brings out red and pink hues, while low light keeps leaves green and growth less compact. Consider adding full-spectrum LED aquarium lighting for optimal results.

CO2 & Nutrient Needs

• CO2 Injection: Highly recommended for strong growth and red coloring
• Fertilizers: Liquid fertilizers (NPK and micro elements), root tabs as needed
• Substrate: Nutrient-rich substrates are ideal but not required

Rotala rotundifolia will adapt to lower-tech tanks, but it truly flourishes (and colors up!) with consistent CO2 and comprehensive fertilization.

Water Parameters

• Temperature: 20–28°C (68–82°F)
• pH: 6.0–7.5
• GH/KH: Soft to moderately hard water

How to Plant Rotala Rotundifolia

1. Separate the stems into groups of 4-5.
2. Trim any damaged tips and extra-long roots.
3. Plant with planting tweezers 2–3 centimeters apart for bushy growth.
4. Press gently into the substrate to prevent floating.

Within a few weeks, your stems will develop side shoots, filling in gaps and creating a lush look—perfect for Dutch aquascapes or natural layouts.

Trimming & Propagation Tips

Regular maintenance is key for vibrant, compact growth:

• Use aquascaping scissors to trim tops when stems reach the surface.
• Replant healthy trimmings to thicken existing groups.
• Remove leggy or shaded lower stems to prevent decay and shading.
• Prune frequently to encourage branching and more vivid coloration.

Propagating Rotala rotundifolia is simple—just take cuttings with at least three nodes and plant them into the substrate.

Common Problems and Solutions

• Stunted Growth: Likely due to lack of CO2 or insufficient nutrients. Dose fertilizers and improve CO2 distribution.
• Pale Leaves: Indicates iron or micronutrient deficiency. Adjust fertilization regime.
• Melt or Rot: Watch for ammonia spikes or poor circulation. Regular water changes and pruning help prevent this.
• Algae Growth: Ensure balanced lighting and nutrient dosing. Incorporate algae eaters or algae-cleaning crew if necessary.

Design Inspiration: Aquascaping with Rotala Rotundifolia

Get creative with color and texture in your aquascape. Mass plantings of Rotala rotundifolia provide a vibrant backdrop, while staggered trimming creates beautiful sloped banks of color. Pair with midground plants like Bucephalandra and foreground carpeting plants for an immersive, layered effect. Experiment with varying planting densities and lighting angles to create unique visual interest.
