Polypterus Cuvier's Bichir (70mm)

Polypterus curviceps (Curvier Bichir)

Description:

• Appearance:

  • Size: Typically grows up to 8-12 inches (20-30 cm). In larger tanks and with optimal conditions, some individuals can reach up to 16 inches (40 cm).
  • Color: Generally dark brown to olive with light-colored, contrasting bands or spots. The pattern and color can vary slightly depending on individual and environmental factors.
  • Body Shape: Elongated and cylindrical with a series of dorsal finlets resembling small, sharp-edged plates. The body is covered in heavy, armored scales.

• Behavior:

  • Activity Level: Mostly slow-moving but active, especially during feeding times. They are nocturnal and more active at night.
  • Social Behavior: Can be somewhat territorial and might show aggression towards other bichirs or fish with similar body shapes. They are generally solitary.

Care Requirements:

• Tank Size:

  • Minimum: 75 gallons (284 liters) for smaller individuals. Larger specimens or multiple bichirs may require a 125-gallon (473 liters) or larger tank.

• Tank Setup:

  • Substrate: Use soft sand or smooth gravel. Avoid sharp or rough substrates to prevent injury.
  • Decorations: Include hiding spots such as driftwood, rocks, and caves. Provide a variety of structures to mimic their natural habitat and offer security.
  • Plants: Can include live or artificial plants. Ensure they are securely anchored and sturdy enough to withstand the bichir's activity.

• Water Parameters:

  • Temperature: 75-82°F (24-28°C). Maintain a stable temperature within this range.
  • pH: 6.0-8.0. They are adaptable to a range of pH levels but prefer slightly acidic to neutral water.
  • Hardness: Soft to moderately hard water.
  • Filtration: Strong filtration is necessary to maintain water quality. Ensure that the filter provides efficient mechanical and biological filtration without creating strong currents.

• Diet:

  • Primary Food: Carnivorous. Offer a varied diet of high-quality pellets, live or frozen foods such as worms, small fish, and crustaceans.
  • Supplemental Food: Occasional treats like small shrimp or other protein-rich foods.

• Behavioral Considerations:

  • Compatibility: Suitable with other large, peaceful fish. Avoid keeping with small fish that may be seen as prey.
  • Tank Mates: Good companions include other large tetras, catfish, and non-aggressive larger species. Avoid aggressive or fin-nipping tank mates.

• Tank Maintenance:

  • Water Changes: Regular water changes of 25-30% weekly are crucial to maintain water quality and reduce waste buildup.
  • Cleaning: Keep the tank clean and ensure the filter is functioning well. Remove uneaten food to prevent water quality issues.

• Health Care:

  • Observation: Monitor for signs of illness or stress, such as changes in behavior, loss of appetite, or visible abnormalities.
  • Treatment: Maintain optimal water quality to prevent diseases. Consult an aquarium specialist if health issues arise.

• Additional Notes:

  • Lifespan: Can live up to 10-15 years with proper care.
  • Breeding: Breeding in captivity is rare. Optimal water conditions and tank setup may encourage spawning, but it typically requires specific conditions.
