Rohan’s Teardrop Barb (Dawkinsia rohani):
Introduction:
- Rohan’s Teardrop Barb, scientifically known as Dawkinsia rohani, is a striking freshwater fish native to the rivers of India. Named after Dr. Rohan Pethiyagoda, this species is beloved for its vibrant colors, especially the distinctive black teardrop marking on its body. Known for its active and schooling behavior, this fish is an ideal choice for community tanks and adds an exotic splash of color to any setup.
1. Natural Habitat and Behavior
- Dawkinsia rohani is found in fast-flowing rivers and streams in India. It inhabits areas with plenty of plant life and submerged vegetation.
- This species is peaceful and thrives in groups. Like most barbs, they are active swimmers and prefer to be in schools of at least six or more. Their social behavior is crucial to reducing stress, and they exhibit playful interactions when housed in a group.
2. Aquarium Setup
- Tank Size: A minimum of 40 gallons is recommended for a group of six or more Rohan’s Teardrop Barbs. A larger tank will help accommodate their energetic swimming and schooling behavior.
- Substrate: Soft sand or gravel mimicking their natural riverbed habitat is ideal. Avoid sharp substrate that could damage their barbels.
- Decor: Provide plenty of plants, driftwood, and rocks to replicate their natural habitat and offer them places to explore. Make sure there is enough open swimming space for their active nature.
- Water Conditions: This species thrives in slightly acidic to neutral water (pH 6.0-7.5), with temperatures between 72°F and 79°F. Moderate water flow is essential, reflecting their natural environment.
- Lighting: Moderate lighting is ideal to support plant growth and keep the barbs comfortable in their environment.
3. Diet and Feeding
- Rohan’s Teardrop Barb is an omnivorous species with a varied diet. Feed them a mix of high-quality flake or pellet foods, supplemented with live or frozen foods like brine shrimp, daphnia, and bloodworms.
- They will also appreciate plant-based foods, so include blanched vegetables such as spinach or spirulina-based pellets to balance their diet.
- Feed them small portions twice a day, ensuring they consume everything within a few minutes to maintain water quality.
4. Compatibility with Other Fish
- Rohan’s Teardrop Barb is generally peaceful and does well in a community tank with other similarly sized, non-aggressive species. Ideal tank mates include tetras, rasboras, other peaceful barbs, and corydoras catfish.
- Avoid housing them with slow-moving or long-finned species, such as bettas or guppies, as barbs may occasionally nip fins.
- Keep them in groups of six or more to encourage natural schooling behavior and reduce stress.
5. Common Challenges and Tips
- Ensure the tank is properly cycled before introducing Rohan’s Teardrop Barbs, as they can be sensitive to changes in water quality.
- Regular water changes are important to maintain optimal water conditions, especially in a densely stocked tank.
- Barbs are active swimmers, so a tank with a secure lid is essential to prevent them from jumping out.
Conclusion:
- Rohan’s Teardrop Barb is a colorful and lively addition to any freshwater aquarium. Its peaceful nature and schooling behavior make it perfect for community tanks, while its striking appearance adds visual interest.
- With proper care, including maintaining water quality and providing a varied diet, these barbs will thrive and bring energy to your aquarium for years to come.
