Dennerle - Rotala rotundifolia 'Blood Red' is available for pre-order – please confirm stock before ordering!
Introduction:
Rotala rotundifolia 'Blood Red', commonly known as Blood Red Rotala, is a vibrant and eye-catching cultivar of the popular Rotala rotundifolia species. Native to Southeast Asia, this variety is specifically selected for its deep red to crimson leaf coloration under high light and nutrient-rich conditions. Its narrow, pointed leaves grow in opposite pairs along slender stems and create a dramatic, vertical accent in planted aquariums. With proper care, it forms dense, colorful clusters, making it a favorite for Dutch-style and high-contrast aquascapes.
Care Requirements:
Water Parameters:
Temperature: 22–28°C
pH Range: 5.5–7.5
Hardness: Soft to moderately hard water (2–10°dGH)
Nutrient Requirements:
Blood Red Rotala is a heavy feeder when grown under high light and CO₂-enriched conditions. It requires a nutrient-rich substrate and consistent water column fertilization, particularly with iron and micronutrients to maintain its red coloration. CO₂ injection is essential for deep pigmentation and compact growth.
Tank Setup:
Ideal for the midground to background of planted aquariums, this plant thrives in aquasoil or enriched fine gravel. High lighting is mandatory to achieve its trademark blood-red hue—lower light levels will result in greener, less vibrant growth. Moderate water flow supports even nutrient distribution and promotes upright stem development.
Care Tips:
Trim regularly to encourage bushy, lateral growth and replant healthy tops to thicken out the plant group. Remove lower leaves if shaded to maintain an attractive stem base. Ensure stable CO₂ and nutrient dosing to prevent color fading and stunted growth. Avoid overshadowing by taller species to keep the intense red tones prominent.
Rotala rotundifolia 'Blood Red' adds bold, fiery color and elegant vertical structure to any aquascape. Its striking presence and rich pigmentation make it a standout plant for experienced aquarists looking to create contrast and depth in their planted aquarium layouts.
