Description
Bala Shark – Balantiocheilos melanopterus
Introduction:
The Bala Shark (Balantiocheilos melanopterus) is a popular freshwater fish known for its sleek, silver body and striking black-edged fins. Although not a true shark, its torpedo-shaped body and active swimming style earn it the name. Reaching sizes up to 12-14 inches (30-35 cm) in captivity, the Bala Shark requires a spacious tank and is best suited to experienced aquarium hobbyists.
1. Natural Habitat and Behavior
Originating from rivers and lakes in Southeast Asia, the Bala Shark inhabits clear, fast-moving waters. This active, schooling fish thrives when kept in groups of five or more, displaying social behaviors that make them fascinating to watch. However, their large size and energetic nature require significant swimming space.
2. Aquarium Setup
A 125-gallon tank or larger is recommended to house a small school of Bala Sharks comfortably. They prefer soft substrates, like sand or fine gravel, along with open areas for swimming. Decorate with sturdy plants, driftwood, and rocks around the edges. Bala Sharks thrive in water temperatures of 72-82°F (22-28°C) and a pH of 6.5-7.5. Efficient filtration and moderate water flow are crucial, as they are sensitive to water quality and appreciate oxygenated water.
3. Diet and Feeding
Bala Sharks are omnivores and have hearty appetites. Offer a mix of high-quality flakes or pellets, along with frozen or live foods like bloodworms, brine shrimp, and daphnia for protein. They also enjoy occasional vegetable matter, such as blanched spinach or zucchini. Feed them once or twice daily, providing enough food to satisfy their active metabolism.
4. Compatibility with Other Fish
Known for their generally peaceful nature, Bala Sharks are excellent community fish when kept with similarly sized, non-aggressive species. Ideal tank mates include larger tetras, gouramis, barbs, and rainbowfish. Avoid small fish that may be mistaken as food, as well as overly aggressive species that could stress them.
5. Common Challenges and Tips
- Large Size Requirement: Ensure your tank is large enough to house a group, as Bala Sharks can become stressed and unhealthy if kept in insufficient space.
- Water Quality Sensitivity: Regular water changes and a strong filtration system are essential to keep Bala Sharks healthy.
- Avoiding Small Tank Mates: Due to their size and predatory instincts, they may accidentally consume smaller fish.
Conclusion
The Bala Shark (Balantiocheilos melanopterus) is a stunning, active addition for those able to meet its space and social needs. With the right tank setup, compatible tank mates, and a varied diet, this eye-catching fish can thrive and provide endless entertainment in a large home aquarium.
