Dragon’s Tongue – Hemigraphis repanda
Introduction
Dragon’s Tongue (Hemigraphis repanda) is a striking, fast-growing aquatic plant prized for its unique appearance and vibrant coloration. Native to Southeast Asia, this plant features elongated, lance-shaped leaves that are often tinged with shades of red, purple, and green. Its bold, dragon-like leaf shape gives it a distinct presence in any aquarium. Hemigraphis repanda is a hardy plant that can adapt to a variety of conditions, making it an excellent choice for both beginner and experienced aquarium hobbyists looking for a visually appealing and low-maintenance addition to their aquascape.
1. Natural Habitat and Behavior
In the wild, Hemigraphis repanda thrives in shaded or partially shaded areas of tropical streams and rivers in Southeast Asia. It prefers areas with moderate water movement and soft to slightly acidic water conditions. The plant can grow submerged or emersed and has a trailing growth habit, producing long stems that can easily spread across the substrate. In aquariums, Dragon’s Tongue grows vigorously and can quickly spread throughout the tank, forming dense clumps.
2. Aquarium Setup
- Tank Size: Dragon’s Tongue does well in tanks of all sizes but thrives in medium to large aquariums where it has room to spread. In smaller tanks, it may become invasive if not trimmed regularly.
- Lighting: While it can tolerate low light, Hemigraphis repanda grows best under moderate to bright light, which helps to enhance its colors, especially the purple and red hues. Too little light can lead to slower growth and reduced coloration.
- Water Conditions:
- pH: 6.0–7.5
- Temperature: 72–82°F (22–28°C)
- Hardness: Soft to moderately hard water
- Decor: This plant is flexible and can be used in a variety of aquascaping styles. It works well as a background or mid-ground plant and can also be grown as a floating plant. It requires a substrate with good nutrient content, and it does best with moderate water flow to keep the stems upright.
3. Diet and Feeding
Dragon’s Tongue is relatively low-maintenance when it comes to feeding. It absorbs nutrients through its leaves and roots, so regular water changes are key to maintaining its health. If the plant’s leaves appear pale or growth is slow, adding a liquid fertilizer or providing CO2 supplementation can promote healthier and more vibrant growth. It thrives in aquariums with a balanced ecosystem that offers both dissolved nutrients and organic material in the water column.
4. Compatibility with Other Fish
Hemigraphis repanda is a non-toxic and peaceful plant that can be kept with a variety of fish and invertebrates. It is particularly suitable for community tanks, providing shelter and hiding spots for smaller fish and shrimp. However, it may be uprooted or disturbed by large, active fish. As it is a fast grower, it can also outcompete other slow-growing plants in the tank, so care should be taken to maintain balance in the aquascape. Shrimp and small fish species like tetras, guppies, and bettas are excellent tank mates.
5. Common Challenges and Tips
- Overgrowth: Dragon’s Tongue can grow rapidly under optimal conditions and may take over a tank if not regularly trimmed. To maintain its appearance and shape, frequent pruning is recommended.
- Leaf Yellowing: If the plant’s leaves begin to yellow or show signs of nutrient deficiency, it could be an indication of insufficient lighting or a lack of essential nutrients. Providing more light or supplementing the water with fertilizers should help restore its health.
- Slow Growth: In low light or poor water conditions, Dragon’s Tongue may not thrive. Ensure that it receives the appropriate lighting and nutrients to promote its vibrant growth and coloration.
Conclusion
Dragon’s Tongue (Hemigraphis repanda) is a beautiful and versatile aquarium plant that adds a bold visual statement to any setup. With its unique dragon-like leaves and vibrant colors, it is sure to capture attention in aquascapes. This plant is relatively easy to care for, requiring only moderate light and regular water changes, making it ideal for a wide variety of aquarium setups.
