Description
Black Shark – Labeo chrysophekadion
Introduction:
The Black Shark (Labeo chrysophekadion) is a large, semi-aggressive freshwater fish known for its all-black, torpedo-shaped body and energetic swimming habits. Growing up to 24 inches (60 cm) in the wild and typically reaching 14-20 inches (35-50 cm) in aquariums, the Black Shark is suitable for advanced hobbyists with very large tanks and experience managing aggressive species. With the right setup, it can be a fascinating addition to a well-maintained freshwater tank.
1. Natural Habitat and Behavior
Native to Southeast Asia, the Black Shark thrives in rivers and floodplains with plenty of vegetation and moderate to fast-moving water. In its natural habitat, it is an active bottom-dweller and can be territorial, especially as it matures. Black Sharks are solitary and exhibit high energy, making them well-suited for tanks with ample space to roam.
2. Aquarium Setup
A 125-gallon tank or larger is necessary for a single Black Shark to accommodate its size and territorial nature. Use a sandy or smooth gravel substrate, as they enjoy foraging along the bottom, and provide plenty of hiding spots, such as driftwood, rocks, and large plants. They prefer water temperatures between 72-82°F (22-28°C) and a pH of 6.5-7.5. A powerful filtration system is required to maintain clean water and create mild currents that mimic their natural environment.
3. Diet and Feeding
The Black Shark is an omnivore and requires a varied diet. Offer a mix of high-quality sinking pellets, algae wafers, and vegetable matter such as blanched spinach, zucchini, and cucumber. They will also appreciate protein-rich treats like bloodworms, brine shrimp, and daphnia once or twice a week. Feed in moderate amounts once or twice a day to prevent waste buildup and ensure consistent growth.
4. Compatibility with Other Fish
The Black Shark can be aggressive, especially with fish of similar size, shape, or color. Suitable tank mates include robust, fast-swimming fish such as large barbs, silver dollars, or larger cichlids that can handle some territorial behavior. Avoid pairing them with slow-moving or small, timid fish, as they may be harassed or outcompeted for food. It’s best to house only one Black Shark per tank due to their solitary and territorial nature.
5. Common Challenges and Tips
- Aggression with Age: As Black Sharks mature, they tend to become more territorial. Be prepared to house it alone or with very compatible tank mates in a large aquarium.
- Tank Size Requirement: Their large adult size makes them suitable only for spacious tanks with strong filtration.
- High Filtration Needs: Black Sharks produce significant waste, so regular water changes and a robust filtration system are necessary to maintain water quality.
Conclusion
The Black Shark (Labeo chrysophekadion) is a stunning yet challenging species for experienced hobbyists with large tanks. Its bold appearance and dynamic swimming habits make it an intriguing choice for advanced freshwater setups. With proper care, space, and the right tank mates, the Black Shark can thrive and become a centerpiece in a dedicated aquarium.
