Rotala Vietnam (Rotala sp. Vietnam) Care Guide
Rotala Vietnam is a stunning, versatile plant known for its vibrant colors and delicate, bushy growth. Part of the Rotala genus, this plant offers many varieties, from Rotala rotundifolia to Rotala macrandra, each bringing unique hues and textures to aquascapes. Rotala Vietnam H’ra, a popular variant, is especially prized for its reddish-orange tones. Here’s a detailed care guide to help you grow Rotala Vietnam and other related species like Rotala indica and Rotala H'ra.
Overview
- Scientific Name: Rotala sp. Vietnam
- Common Names: Rotala Vietnam, Rotala H’ra, Rotala Vietnam H’ra, Rotala Red
- Family: Lythraceae
- Origin: Southeast Asia
- Difficulty Level: Moderate
- Growth Type: Stem plant
- Size: Up to 12-20 inches in height
Tank Requirements
- Tank Size: Minimum of 10 gallons; ideally suited for mid-size to larger tanks for best visual impact.
- Placement: Rotala Vietnam and related varieties like Rotala rotundifolia orange juice are ideal for mid-ground or background placement due to their tall, bushy growth.
Water Parameters
- Temperature: 72-82°F (22-28°C)
- pH Level: 5.5-7.5
- Water Hardness: Soft to moderately hard (2-12 dGH)
Rotala Vietnam adapts well to various water conditions, though slightly acidic to neutral water brings out the best colors, especially in varieties like Rotala red and Rotala macrandra.
Lighting Requirements
- Light Level: Moderate to high
- Duration: 8-10 hours per day
High lighting encourages more vibrant colors, particularly in red varieties like Rotala H’ra and Rotala rotundifolia orange juice. Under lower light, these plants may grow slower and display greener tones rather than their iconic reds and oranges.
Substrate and Fertilization
- Substrate: Nutrient-rich substrate is recommended, especially for root growth. While Rotala Vietnam can adapt to sand or gravel, an enriched substrate is ideal.
-
Fertilization:
- Macronutrients: Regular dosing of NPK (Nitrogen, Phosphorus, Potassium) is essential for vibrant growth.
- Micronutrients: Iron helps maintain the reddish coloration seen in varieties like Rotala red and Ludwigia Rotala hybrids.
- CO₂ Injection: Highly recommended. Rotala macrandra and other red varieties develop richer colors and faster growth with CO₂ supplementation.
Routine fertilization helps prevent deficiencies, particularly if Rotala aquarium plants are competing for nutrients in densely planted tanks.
Planting and Propagation
- Planting: Plant each stem individually in the substrate with some spacing to allow horizontal growth. Proper spacing encourages bushier growth, especially in HRA plant types.
- Propagation: Easily propagated through stem cuttings. Cut a healthy stem, and replant it in the substrate. The plant will root and continue growing, filling out the aquascape.
Growth Rate and Maintenance
- Growth Rate: Moderate to fast. With optimal lighting, nutrients, and CO₂, Rotala rotundifolia and Rotala H’ra can grow quickly and require regular trimming.
- Trimming: Frequent trimming encourages bushiness and prevents plants from overshadowing others. Prune the tops to encourage lateral shoots and compact growth.
Removing old or unhealthy leaves also maintains appearance and reduces algae buildup.
Potential Issues
- Melting: Initial melting can occur when Rotala Vietnam is introduced to new conditions. Trim melted leaves, and allow time for acclimation.
- Nutrient Deficiency: Pale or yellowing leaves indicate nutrient deficiencies, particularly iron. Regular dosing helps prevent this.
- Algae Growth: High lighting without balanced CO₂ or nutrients can lead to algae issues. Maintaining a balance between light, CO₂, and nutrients is crucial for a healthy plant.
Compatibility and Tank Mates
- Ideal for: Peaceful community aquariums with small fish and shrimp.
- Avoid: Large, herbivorous fish that may damage the delicate leaves.
Benefits in the Aquarium
- Aesthetic Appeal: Rotala Vietnam adds a vibrant splash of color with its red and orange hues, creating stunning contrast with green plants.
- Oxygen Production: Helps oxygenate the water and contributes to a balanced ecosystem.
- Natural Habitat: Provides shelter for small fish and shrimp, adding to the naturalistic feel of the aquarium.
Conclusion
Rotala Vietnam and its related varieties, including Rotala rotundifolia, Rotala indica, Ammania Bonsai Red, and Ludwigia Rotala hybrids, are excellent choices for aquascapes looking to add color and texture. With stable water conditions, adequate lighting, and consistent nutrient dosing, these plants will flourish and bring life to any aquarium.
