Description
Ghost Shark – Epalzeorhynchos frenatum
Introduction:
The Ghost Shark (Epalzeorhynchos frenatum) is a captivating freshwater fish known for its sleek body, silvery-grey color, and white fins. Typically growing to about 4-6 inches (10-15 cm) in length, this fish is popular in large aquariums due to its unique look and active nature. Ghost Sharks can be territorial, so they are best suited for experienced aquarists who can provide the right environment and tank mates.
1. Natural Habitat and Behavior
The Ghost Shark thrives in clear, fast-moving waters with rocky substrates and ample hiding places. In the wild, they scavenge along the riverbed, looking for food. In the aquarium, Ghost Sharks are known for their semi-aggressive, territorial behavior, especially toward other bottom-dwelling fish, making them solitary yet active inhabitants.
2. Aquarium Setup
To house a Ghost Shark comfortably, a 50-gallon tank or larger is recommended. Set up the tank with a fine gravel or sandy substrate, and add plenty of rocks, driftwood, and plants to create hiding spots and reduce territorial aggression. The water temperature should be maintained between 72-82°F (22-28°C) with a pH level of 6.5-7.5. Strong filtration and good water movement are important, as this replicates the fast-flowing rivers of their natural habitat.
3. Diet and Feeding
Ghost Sharks are omnivorous and thrive on a varied diet. Offer them algae wafers, sinking pellets, and fresh vegetables like zucchini and cucumber as staple foods. Supplement their diet with protein sources like bloodworms, brine shrimp, or daphnia for balanced nutrition. Feed them once daily, providing food that reaches the bottom of the tank where they prefer to feed.
4. Compatibility with Other Fish
Given their territorial nature, Ghost Sharks are best kept with fast-moving, mid-to-top dwelling species like tetras, barbs, and danios. Avoid housing them with other bottom-dwellers or similar species, like other sharks, as this can lead to aggressive interactions. Providing plenty of space and visual barriers will help reduce territorial conflicts in a community setup.
5. Common Challenges and Tips
- Aggression: Ghost Sharks can become more territorial as they mature, particularly toward fish that resemble them. Ensure ample hiding spaces to prevent aggression and consider a larger tank if issues persist.
- Water Quality: Like many freshwater species, Ghost Sharks are sensitive to poor water quality. Regular water changes and efficient filtration are essential.
- Tank Size and Decor: A spacious, well-decorated tank with plenty of hiding spots is important to manage territorial behavior and keep the Ghost Shark healthy.
Conclusion
The Ghost Shark makes an eye-catching and dynamic addition to larger freshwater aquariums. With the right tank setup, compatible tank mates, and careful attention to their territorial needs, they can be a rewarding species for aquarists seeking an active and unique fish. Their behavior and distinct look make them a focal point in any well-maintained setup.
