Alternanthera reineckii ‘Rosanervig’ – TC Cup
Produced by: Sreepadma Aquatic Plants
🌱 Scientific Overview
Alternanthera reineckii ‘Rosanervig’ is one of the most attractive aquatic Alternanthera varieties. It is characterized by its soft pink to light red leaves with clearly visible pink or whitish veins running across the leaf blade, giving it a refined and artistic appearance in planted aquariums.
The plant belongs to the Amaranthaceae family and is widely used in professional aquascaping designs to add strong color contrast and visual depth among green aquatic plants.
🧪 Tissue Culture Technology – TC Cup
This product is cultivated using Tissue Culture (TC Cup) technology by Sreepadma Aquatic Plants, a modern method that guarantees:
- A completely clean and sterile plant, free from:
- Pests
- Snails
- Algae
- Chemical and pesticide residues
- High density of healthy plantlets in each cup
- Better adaptation after planting
- Full safety for sensitive aquatic life such as fish and shrimp
🌍 Natural Habitat
The natural habitat of Alternanthera reineckii includes:
- South America
- Tropical and humid regions
- Riverbanks and slow-moving freshwater bodies
These conditions explain its preference for stable water parameters and nutrient-rich aquatic environments.
🎨 Appearance and Form
- Leaf Color:
- Pink to light red with distinct veins (Rosanervig = pink-veined)
- Leaf Shape:
- Oval to elongated
- Growth Pattern:
- Upright stem plant
- Expected Height:
- 20–40 cm depending on aquarium conditions
📍 Ideal Placement in the Aquarium
- Placement:
- Midground or background
- Commonly used as a color focal point
- Ideal for:
- Dutch-style aquariums
- Nature-style aquascapes
- Competition and display aquariums
💡 Lighting Requirements
- Lighting: Medium to high
- Higher light levels result in:
- Stronger pink and red coloration
- More compact and dense growth
- Low lighting may cause:
- Faded coloration
- Leggy, elongated stems
🌬️ Carbon Dioxide (CO₂)
- Strongly recommended
- Helps with:
- Faster growth
- Enhanced pink coloration
- Prevention of leaf melt
- Can grow without CO₂,
- but coloration will be weaker and growth slower
🌿 Suitable Substrate
Best planted in:
- Nutrient-rich aquarium soil (Active Soil)
- Specialized aquatic plant substrates
- The use of root tabs further enhances growth and coloration
🧂 Fertilization and Nutrition
- Requires:
- Macronutrients (NPK)
- Micronutrients (Iron – Fe is essential for coloration)
- Iron deficiency may cause:
- Faded leaf color
- Yellowing of new growth
🌡️ Water Parameters
- Ideal Temperature:
- 22–28°C
- pH Range:
- 5.5 – 7.5
- Water Hardness:
- Soft to moderately hard
✂️ Planting Instructions (Step by Step)
- Carefully open the TC cup
- Rinse the plant thoroughly to remove all gel residue
- Divide the plant mass into small individual portions
- Plant each portion separately into the substrate
- Leave 2–3 cm spacing between each plant
- Gradually increase lighting and CO₂ during the first week
🔁 Trimming and Replanting
- Once the plant reaches the desired height:
- Trim the top portion
- Replant the cuttings to increase density
- Regular trimming:
- Maintains an attractive shape
- Prevents shading of neighboring plants
⚠️ Important Notes
- Slight color changes are normal during the transition from TC to aquarium conditions
- An adaptation period of 1–3 weeks is expected
- Not recommended for low-light aquariums
✅ Suitable For
- Intermediate to advanced aquarists
- Densely planted aquariums
- Shrimp and sensitive fish tanks
