1. Rotala rotundifolia

Rotala rotundifolia #ad

Overview: Rotala rotundifolia is a versatile and vibrant aquatic plant, beloved for its lush, bushy growth and ability to add dynamic texture to aquascapes. Native to Southeast Asia, its delicate, rounded leaves shift from green to pinkish-red under high light, making it a favorite for creating colorful focal points.

Aquascape Arrangement:

• Placement: Ideal for midground or background roles in aquariums due to its height (20-80 cm). Plant in dense clusters to create a lush, forest-like effect or use as a backdrop to frame shorter plants like foreground carpets.
• Design Tips: Pair with contrasting plants like Anubias or Cryptocoryne for texture variety. Its upright growth complements Dutch-style layouts or natural aquascapes with driftwood accents. Trim regularly to maintain a tidy shape and encourage bushier growth.
• Visual Appeal: The plant’s ability to transition from green to pinkish hues under intense lighting adds depth and vibrancy, especially in high-tech setups.

Care Requirements:

• Lighting: Moderate to high (0.5–1 watt per liter). Higher light enhances reddish coloration.
• CO2: Recommended (10-30 mg/L) for robust growth, though it can survive without supplementation.
• Substrate: Nutrient-rich substrate (e.g., aquasoil) promotes faster growth, but it adapts to gravel with liquid fertilizers.
• Water Parameters: Temperature 20–28°C, pH 6.0–7.5, soft to moderately hard water.
• Maintenance: Trim the tops and replant for propagation. Remove older leaves to prevent algae buildup.
• Challenges: Low light may cause leggy growth; ensure adequate nutrients to avoid pale leaves.

2. Rotala rotundifolia ‘Green’

Overview: A vibrant green variant of Rotala rotundifolia, this plant retains its emerald hue even under high light, offering a fresh, calming presence in aquascapes. Its compact leaves and dense growth make it a go-to for lush, verdant displays.

Aquascape Arrangement:

• Placement: Best in midground or background, growing 20–60 cm tall. Use in tight bunches to form a green wall or as a filler between colorful plants like Ludwigia or red Rotala variants.
• Design Tips: Its consistent green color contrasts beautifully with red or variegated plants, making it ideal for balanced, harmonious layouts. Works well in Iwagumi or jungle-style tanks. Trim to create a stepped effect in multi-layered aquascapes.
• Visual Appeal: The bright, unchanging green adds a sense of tranquility and complements natural elements like rocks or moss.

Care Requirements:

• Lighting: Moderate (0.4–0.8 watts per liter) is sufficient, as it doesn’t require intense light for coloration.
• CO2: Optional but boosts growth rate and density.
• Substrate: Thrives in nutrient-rich substrates but adapts to inert ones with fertilization.
• Water Parameters: Temperature 22–28°C, pH 6.0–7.5, soft to medium hardness.
