The African brown knifefish (Xenomystus nigri) is a unique and fascinating freshwater fish that can make a rewarding addition to the right aquarium. Native to the slow-moving, murky waters of West and Central Africa, these nocturnal predators have captivated aquarists with their sleek, torpedo-like bodies and intriguing hunting behavior. This comprehensive guide will delve into the specifics of African Brown Knifefish Care, equipping you with the knowledge to provide a thriving environment for these captivating creatures.
Understanding the African Brown Knifefish
Before we dive into the specifics of care, let’s get acquainted with the African brown knifefish. Unlike most fish that rely on sight to navigate and hunt, these nocturnal marvels possess a unique sensory organ called a “knifefish” due to its long, compressed body shape, which resembles a knife. This organ allows them to detect the electrical fields generated by other organisms, enabling them to navigate murky waters and locate prey with remarkable precision, even in complete darkness.

Setting up the Ideal Aquarium
Creating a comfortable and stimulating habitat is crucial for the well-being of your African brown knifefish. Here’s a breakdown of the key factors to consider:
Tank Size:
As adults can reach up to 15 inches in length, a spacious tank is essential. A minimum tank size of 55 gallons is recommended for a single specimen, with larger tanks being necessary for multiple fish.
Water Parameters:
African brown knifefish thrive in slightly acidic to neutral water with a pH range of 6.5 to 7.5. Maintain a temperature between 75-82°F (24-28°C) and ensure proper filtration to maintain excellent water quality.
Substrate and Decorations:
These fish prefer a soft, sandy substrate that won’t injure their sensitive underbellies. Provide ample hiding spaces using caves, rocks, driftwood, and dense vegetation. Java ferns and Anubias are excellent plant choices as they can tolerate low light conditions.
Lighting:
Since African brown knifefish are nocturnal, they do not require bright lighting. In fact, subdued lighting is preferable. You can achieve this by using floating plants or opting for a dimmable LED light.

Feeding Your African Brown Knifefish
These nocturnal predators are carnivores with a preference for live food. In the wild, their diet primarily consists of insects, worms, and small crustaceans.
Live Food Options:
- Bloodworms
- Blackworms
- Brine shrimp
- Small earthworms
- Feeder fish (use sparingly)
Weaning onto Prepared Foods:
While initially hesitant, you can try to wean your knifefish onto prepared foods like frozen and freeze-dried options. High-quality sinking pellets specifically designed for carnivorous fish can also be offered.
Feeding Frequency:
Feed your adult African brown knifefish once every other day, offering enough food that they consume within a few minutes. Adjust the feeding frequency and quantity based on their age, size, and activity level.
Compatibility and Tank Mates
While peaceful in nature, African brown knifefish are best kept in a species-only tank or with carefully chosen tank mates.
Suitable Tank Mates:
- Larger, peaceful tetras like Congo tetras
- Larger barbs like tiger barbs
- Certain catfish species, such as Synodontis catfish
- Avoid small, aggressive, or fin-nipping species
Observation is Key:
Always observe new additions to the tank closely for any signs of aggression or bullying. Ensure all fish have ample space to establish their territories.
