Description
Red Rubin Sword – Echinodorus red rubin
Introduction
The Red Rubin Sword (Echinodorus red rubin) is a stunning aquatic plant that showcases a mix of vibrant red, bronze, and green hues. With a height of 12–20 inches (30–50 cm), it serves as an excellent midground or background plant in larger aquariums. This hybrid variety is prized for its adaptability and striking coloration, making it a popular choice for aquascapers and hobbyists seeking a bold aesthetic feature.
1. Natural Habitat and Behavior
Although Echinodorus red rubin is not found in the wild—it is a cultivated hybrid—its parent species originate from slow-moving rivers and flooded areas of South and Central America. Like its relatives, it thrives in nutrient-rich substrates and grows both submerged and emersed. In aquariums, it forms broad leaves that provide shelter for fish and create a dramatic visual impact.
2. Aquarium Setup
- Tank Size: Minimum 20 gallons (75 liters) to accommodate its growth.
- Substrate: Nutrient-rich soil or fine gravel with root tabs for optimal growth.
- Decor: Ideal as a focal point or planted in groups to enhance the aquarium’s natural look.
- Water Conditions:
- Temperature: 72–82°F (22–28°C)
- pH: 6.5–7.5
- Hardness: Soft to moderately hard water
- Lighting: Moderate to high; intense lighting brings out the plant’s vivid red coloration.
3. Diet and Feeding
The Red Rubin Sword is a heavy root feeder. Use nutrient-dense substrates or add root tabs to support its growth. Supplementing with liquid fertilizers rich in iron and micronutrients will maintain its vibrant colors. CO₂ injection can promote faster and healthier growth but is not a strict requirement.
4. Compatibility with Other Fish
This plant is highly compatible with a variety of freshwater fish, including:
- Peaceful community species such as tetras, rasboras, and gouramis.
- Bottom dwellers like Corydoras and kuhli loaches.
- Herbivores like plecos, as the tough leaves resist grazing.
Avoid aggressive herbivorous fish such as goldfish and large cichlids that may damage or uproot the plant.
5. Common Challenges and Tips
- Color Fading: Insufficient lighting or iron deficiency may cause the red coloration to fade. Provide intense lighting and iron supplements to restore vibrancy.
- Algae Growth: High lighting can lead to algae on the leaves. Control algae with regular maintenance and algae-eating tank mates.
- Slow Growth: This plant grows moderately under standard conditions but can be encouraged with consistent fertilization and CO₂ injection.
Conclusion
The Red Rubin Sword (Echinodorus red rubin) is a visually striking addition to any freshwater aquarium. Its vibrant coloration, ease of care, and adaptability make it a standout choice for aquarists of all experience levels. With proper care and attention, it can thrive as a stunning centerpiece or complementary plant in your aquascape.
