The Delhezi Bichir (Polypterus delhezi), also known as the Armored Bichir or Barred Bichir, is a prehistoric-looking freshwater fish belonging to the Polypteridae family. Here are key details about this fascinating species:
• Maximum Size: They can grow up to 14-18 inches (35-45 cm) in captivity, though wild specimens may be slightly larger.
• Native Habitat: Found in the Congo River Basin in Central Africa, mainly in slow-moving waters with muddy or sandy bottoms.
• Growth Rate: Slow to moderate; it can take several years to reach full size.
• Lifespan: 15-20 years with proper care, though some have lived longer in captivity.
• Diet: Carnivorous – they primarily feed on small fish, insects, crustaceans, and worms. In captivity, they accept live, frozen, and high-quality carnivore pellets.
• Breeding Season: Breeding is rare in captivity, but it typically occurs during the rainy season in the wild. Males chase and fertilize eggs, which are scattered among plants.
• Best Tank Mates: Since they are predatory, they should be housed with similarly sized or larger peaceful but robust fish. Good tank mates include:
• Other bichirs
• Large cichlids (such as Oscar, Severum, or peaceful South American cichlids)
• Arowanas (if tank size allows)
• Large catfish (such as Synodontis or plecos)
• Silver dollars
• Ropefish
Avoid keeping them with small fish like tetras, guppies, or anything that can fit in their mouth, as they will be eaten.
