Description
Tire-Track Eel (Mastacembelus armatus)
Introduction:
The Tire-Track Eel (Mastacembelus armatus), named for its distinctive track-like markings, is a popular species for large aquariums. Known for its peaceful demeanor and burrowing habits, this eel can reach sizes of up to 30 inches (76 cm) in captivity, making it a fascinating and interactive choice for experienced hobbyists who can meet its spacious tank needs.
1. Natural Habitat and Behavior of Tire-Track Eels
Tire-Track Eels are native to the rivers, streams, and floodplains of Southeast Asia. They inhabit slow-moving waters with dense vegetation and soft, muddy substrates, where they burrow and hunt for food. In aquariums, they exhibit similar behaviors, spending much of their time hiding or burrowing during the day and becoming more active at night. These eels are known for their shy and secretive nature, preferring to stay out of sight until feeding time.
2. Tire-Track Eel Aquarium Setup
- Tank size: Tire-Track Eels can grow up to 2-3 feet in length, making a minimum tank size of 125 gallons necessary for adult specimens. Larger tanks are ideal for long-term care.
- Substrate: A soft sand or fine gravel substrate is recommended to allow for safe burrowing. Sharp substrates should be avoided to prevent injury.
- Decor: Create plenty of hiding spots with rocks, driftwood, and PVC pipes. Secure decorations firmly, as the eel may shift them while burrowing or exploring.
- Water conditions: Maintain water temperatures between 74°F and 82°F, with a pH of 6.5 to 7.5. Tire-Track Eels prefer soft to moderately hard water.
- Lighting: As nocturnal creatures, Tire-Track Eels thrive in low to moderate lighting, which replicates their natural, shaded habitat.
3. Diet and Feeding of Tire-Track Eels
Tire-Track Eels are carnivores, requiring a protein-rich diet. They should be fed live or frozen foods such as bloodworms, earthworms, shrimp, and small fish. They may also accept prepared foods like sinking carnivore pellets, but live and frozen options should form the bulk of their diet. Feeding them in the evening or at night aligns with their nocturnal feeding habits.
4. Compatibility with Other Fish
Tire-Track Eels are generally peaceful but can be territorial, especially in smaller tanks. They are best housed with large, robust fish like cichlids, catfish, or other spiny eels. Avoid keeping them with smaller fish that may be seen as food. Providing ample hiding spaces and maintaining a large enough tank can help reduce territorial aggression and ensure a harmonious tank environment.
5. Common Challenges and Tips
- Shyness: Tire-Track Eels are naturally shy and can take time to adjust to their environment. Offering plenty of hiding places will help them feel more secure.
- Escape risk: These eels are excellent escape artists. Ensure the tank is equipped with a secure lid to prevent escapes.
- Water quality: Tire-Track Eels are sensitive to poor water conditions, so consistent water changes and proper filtration are necessary.
- Feeding preferences: While they can be picky about accepting non-live food, patience and a gradual transition can help them adapt to prepared foods.
Conclusion
The Tire-Track Eel (Mastacembelus armatus) is a unique and fascinating species that can thrive in a well-maintained freshwater aquarium. With its intricate patterning and nocturnal behavior, it adds an element of intrigue to any tank. However, due to its size and specific care requirements, this species is best suited for experienced aquarists who can provide a large tank, a varied diet, and the right environment. By following this care guide, you’ll be well-equipped to enjoy the company of this remarkable spiny eel in your home aquarium.
