Ansorgii Bichir – A Unique and Ancient Freshwater Predator

The Ansorgii Bichir is a fascinating freshwater fish known for its elongated body, prehistoric appearance, and predatory behavior. Native to West Africa, this species (*Polypterus ansorgii*) is highly prized among aquarists for its striking coloration, armored scales, and fascinating behavior. Ansorgii Bichirs are best suited for large aquariums and are admired for their low-maintenance care and unique presence.

Appearance
Ansorgii Bichirs have an elongated, cylindrical body covered in thick, armored scales. Their coloration typically ranges from gray to olive green with darker vertical bands along the body. They have a series of dorsal finlets along their back and a powerful tail for swimming. Adults can grow to 20–24 inches in captivity, with some reaching larger sizes under optimal conditions, giving them a prehistoric and dramatic look.

Temperament and Behavior
Ansorgii Bichirs are generally peaceful toward similarly sized tankmates but are predatory and may eat smaller fish. They are nocturnal and mostly bottom dwellers, often hiding among rocks, driftwood, and dense plants during the day. They are intelligent, capable of recognizing feeding times, and will actively hunt for food.

Tank Requirements
Tank Size A minimum of 150 gallons is recommended for a single adult, with larger tanks preferred for multiple individuals or to accommodate their size and swimming behavior.
Water Conditions Slightly acidic to neutral pH 6.5–7.5 with soft to moderately hard water.
Temperature 75–82°F 24–28°C for optimal health and activity.
Aquascape Provide open swimming areas with caves, driftwood, and sturdy decorations. A soft substrate is recommended to prevent damage to their delicate belly and ventral fins.

Diet
Ansorgii Bichirs are carnivorous and thrive on a protein-rich diet. Offer a variety of foods including live or frozen fish, shrimp, worms, and specialized carnivorous pellets. Feeding should be done once daily for juveniles and 2–3 times per week for adults. Avoid overfeeding to maintain water quality.

Tankmates
Suitable tankmates are large, non-aggressive fish that cannot be swallowed. Avoid small fish or invertebrates that may be seen as prey. Compatible species include other large bichirs, arowanas, and large cichlids.
