Description
Royal Clown Knifefish – Chitala blanci
Introduction:
The Royal Clown Knifefish (Chitala blanci) is a captivating, rare species admired for its sleek, silver body and fewer but prominent spots compared to other knifefish species. Growing up to 24-30 inches (60-75 cm) in captivity, this large, predatory fish is suited to experienced aquarists with the space and resources to accommodate its unique needs.
1. Natural Habitat and Behavior
Native to river systems in Southeast Asia, particularly the Mekong Basin, the Royal Clown Knifefish thrives in slow-moving, murky waters rich in vegetation. This nocturnal predator has a solitary and territorial nature, primarily hunting at night. In the aquarium, it often exhibits graceful, undulating movements and may be shy, especially in brightly lit tanks.
2. Aquarium Setup
A tank of at least 180 gallons is necessary for a Royal Clown Knifefish, offering room to swim and mature comfortably. Ideal water conditions include a pH of 6.0-7.5 and temperatures between 75-82°F (24-28°C). Use a soft, sandy substrate and incorporate hiding places, such as rocks, driftwood, or PVC pipes, to make the fish feel secure. Dim lighting is preferable, as this species is sensitive to bright lights and tends to be more active in subdued conditions.
3. Diet and Feeding
Royal Clown Knifefish are carnivores, mainly feeding on smaller fish and invertebrates. In an aquarium setting, they thrive on a diet of live or frozen foods, including shrimp, fish fillets, earthworms, and high-quality carnivore pellets. Feeding should be done in the evening or during times when the fish is most active. Avoid overfeeding, as they can easily gain excess weight if given large quantities of food regularly.
4. Compatibility with Other Fish
While generally solitary, Royal Clown Knifefish can cohabit with other large, peaceful to semi-aggressive species that won’t be intimidated by their presence, such as Arowanas, large cichlids, or robust catfish. Avoid small or slow-moving fish, as these will likely be seen as prey. Ensure plenty of tank space and hiding spots to prevent territorial aggression.
5. Common Challenges and Tips
- Large Tank Requirement: These fish need a spacious tank to thrive, so be prepared for a long-term commitment with frequent upgrades.
- Stress from Bright Lights: Bright lights can stress them, so opt for dim lighting or create shaded areas in the tank.
- Sensitive to Poor Water Quality: Like most large fish, they are susceptible to ammonia and nitrate buildup, making consistent water changes and quality filtration essential.
Conclusion
The Royal Clown Knifefish (Chitala blanci) is an exquisite species, well-suited to spacious aquariums and aquarists with an appreciation for its unique characteristics. With its graceful movements and striking appearance, this fish makes a fascinating addition to any advanced freshwater setup. Providing a calm, well-maintained environment is key to its well-being and longevity.
