Rotala Blood Red

About Rotala Blood Red

Rotala Blood Red is one of the most spectacular red stem plants available for planted aquariums, prized for its intense crimson to deep scarlet foliage. A premium cultivar of Rotala rotundifolia, this variety is renowned for developing brilliant red leaves even under moderate conditions, while high lighting and CO₂ injection produce an extraordinary blood-red appearance that makes it a true centrepiece in any aquascape.

Its slender stems and fine leaves create a soft, flowing texture that contrasts beautifully with broader-leaved plants and lush green carpets. When planted in groups, Rotala Blood Red forms dense, colourful bushes that add depth, movement, and vibrant colour to Dutch-style aquascapes, Nature Aquariums, and high-end planted layouts.

Rotala Blood Red thrives in nutrient-rich aquariums with moderate to high lighting. Although it can grow without CO₂ injection, supplemental CO₂, regular fertilisation, and stable water parameters dramatically improve growth rate, leaf density, and colour intensity. Frequent trimming encourages side shoots, resulting in thick, compact bushes ideal for aquascaping.

Its fast growth also makes it an excellent nutrient absorber, helping reduce excess nitrates and improve overall aquarium stability.

Elegant, colourful, and highly rewarding, Rotala Blood Red is one of the finest red stem plants for freshwater aquascapes.

Frequently Asked Questions

Does Rotala Blood Red require CO₂?

No. It can grow without CO₂, but supplementation significantly improves growth, leaf density, and the rich blood-red colouration.

Why isn't my Rotala Blood Red turning red?

Strong lighting, stable CO₂, and adequate nutrients—particularly iron and trace elements—are essential for developing its intense crimson colour. Lower light often results in orange or greenish foliage.

How do I propagate Rotala Blood Red?

Trim healthy stems and replant the cuttings into the substrate. New roots will quickly form from the stem nodes, allowing the plant to spread.

Is Rotala Blood Red suitable for beginners?

Yes, but it performs best in well-maintained planted aquariums. Beginners can grow it successfully, although achieving its brightest colours requires higher lighting and good nutrient management.

How often should I trim Rotala Blood Red?

Regular trimming every few weeks encourages dense, bushy growth and prevents the lower stems from becoming shaded.

Common Mistakes

Insufficient lighting

Low light results in green or pale orange leaves and leggy growth.

Poor nutrient availability

As a fast-growing stem plant, Rotala Blood Red benefits from regular dosing of macronutrients, micronutrients, and iron.

Inconsistent CO₂

Fluctuating CO₂ levels can stunt growth and increase the risk of algae developing on the leaves.

Planting stems too closely

Leave small gaps between stems to improve water circulation and allow light to reach the lower leaves.

Neglecting regular trimming

Without pruning, the lower portions of the plant may become shaded, causing leaf loss and reducing its attractive bushy appearance.
