Description
Ornate Bichir – Polypterus ornatipinnis
Introduction:
The Ornate Bichir, scientifically known as Polypterus ornatipinnis, is a stunning freshwater species prized for its prehistoric appearance and intricate patterns. Growing up to 24 inches (60 cm) in length, this nocturnal predator is a fascinating addition to large aquariums, making it a favorite among experienced hobbyists.
1. Natural Habitat and Behavior
The Ornate Bichir hails from slow-moving rivers, lakes, and swamps in Central and East Africa. It thrives in oxygen-depleted waters, using its primitive lungs to breathe air. These bottom-dwelling fish are primarily nocturnal, spending the day hidden among plants or decor and becoming more active during feeding times at night.
2. Aquarium Setup
- Tank Size: A minimum of 100 gallons (380 liters) is recommended for a single adult.
- Substrate: Use soft sand or fine gravel to protect their sensitive underbelly.
- Decor: Provide driftwood, rocks, and caves to mimic their natural habitat and offer hiding spots.
- Water Conditions:
- Temperature: 75–82°F (24–28°C)
- pH: 6.5–7.5
- Hardness: 5–20 dGH
- Filtration: A strong canister filter ensures clean water but avoid strong currents.
- Lighting: Keep the lighting subdued to replicate their natural environment and reduce stress.
- Lid Requirement: Bichirs are excellent escape artists. Use a tight-fitting lid to prevent escapes.
3. Diet and Feeding
As carnivorous predators, Ornate Bichirs thrive on a protein-rich diet:
- Primary Foods: Live or frozen foods like bloodworms, shrimp, and fish fillets.
- Occasional Treats: Small feeder fish or earthworms.
- Feeding Tips: Feed them 2–3 times per week, preferably during the evening when they’re most active. Avoid overfeeding to maintain water quality.
4. Compatibility with Other Fish
- Ideal Tank Mates: Other large, non-aggressive species like Arowanas, large catfish, and peaceful cichlids.
- Avoid: Small fish that can fit into their mouth, as they will likely be seen as prey.
- Behavior: While generally peaceful, they can become territorial with other bottom-dwelling species. Provide ample hiding spots to reduce conflicts.
5. Common Challenges and Tips
- Water Quality: Ornate Bichirs are sensitive to poor water conditions. Perform weekly 25–50% water changes.
- Oxygenation: Ensure good aeration as they rely on both gill and lung breathing.
- Injury Risks: Sharp decor can damage their soft scales and underbelly; choose smooth materials.
- Escaping: Always check your lid and aquarium seals, as their escape attempts are common.
Conclusion:
The Ornate Bichir is a captivating species that brings a prehistoric charm to any large aquarium. With its unique patterns and fascinating behaviors, it’s a rewarding choice for aquarists willing to meet its specific care needs. By providing a spacious tank, a protein-rich diet, and a secure environment, you can enjoy the presence of this living fossil for years to come.
