Rotala H’ra – H’ra Rotala

Rotala H’ra is a stunning stem plant admired for its vibrant red-orange to pink leaves and delicate, fine-textured stems. Native to Southeast Asia, it is a favorite among aquascapers for creating striking midground or background color contrasts in high-tech planted aquariums. Its compact growth and vivid coloration make it a dramatic focal point when properly cared for.

Lighting

• High Lighting: Essential to bring out the plant’s red-orange hues. Under lower light, leaves remain green and stems may elongate, losing compactness.

Water Parameters

• Temperature: 22–28 °C; prefers stable, moderate-to-warm conditions.

• pH: 6.0–7.5, slightly acidic to neutral water is ideal.

• Water Hardness: Soft to moderately hard (2–12 dGH) is preferred.

Substrate

• Nutrient-Rich Substrate: Thrives in aquasoil or enriched substrate; root tabs recommended if planting in inert gravel or sand.

• Depth: 5–7.5 cm (2–3 inches) substrate allows strong root anchoring and nutrient absorption.

CO₂ and Fertilization

• CO₂: Highly recommended for faster, compact growth and vibrant coloration.

• Fertilization: Regular dosing of macronutrients and iron-rich micronutrients supports healthy stems and rich red hues.

Growth and Maintenance

• Growth Rate: Fast under high light and CO₂; produces bushy stems when trimmed regularly.

• Pruning: Trim the tops to encourage branching and maintain dense, colorful clusters. Replant cuttings to expand coverage.

Placement in Aquarium

• Midground / Background: Ideal for adding vertical color contrast behind green carpets and foreground plants. Works well as a striking centerpiece in smaller aquascapes.

Propagation

• Stem Cuttings: Trim healthy stems and replant in substrate. New roots form quickly under proper conditions.

Water Flow and Circulation

• Moderate Flow: Supports healthy stem development and prevents debris accumulation on leaves.

Algae Control

• Prevention: Balanced lighting, nutrients, and CO₂ reduce algae growth on fine stems. Avoid excessive light without adequate nutrient supply.

Compatibility

• Community Tank Friendly: Safe with most peaceful fish and invertebrates. Avoid large or digging species that may damage delicate stems.

With proper care, Rotala H’ra will create a striking, colorful midground or background display, adding depth, vibrancy, and movement to your aquascape.

Interesting Fact: The intensity of Rotala H’ra’s coloration depends heavily on light, CO₂, and nutrients. Under optimal conditions, stems display a vivid red-orange gradient, making it one of the most eye-catching plants for high-tech aquascapes. Its fine foliage also provides shelter for small fish and shrimp.
