Apteronotus albifrons

The Black Ghost Knifefish is a fascinating and uniquely shaped freshwater fish originating from the river basins of South America. Its common name comes from its deep black, scaleless body and its ghostly, flowing movements. Instead of swimming like a typical fish, it propels itself using a long, undulating fin that runs along the bottom of its body, allowing it to move forwards and backwards with equal grace. This makes it a captivating spectacle in any aquarium. Due to its eventual large size, a very substantial tank is required to keep one happy and healthy into adulthood. They are nocturnal by nature, preferring to hide during the day in caves or long tubes and becoming more active at night. Because they can be territorial, especially with their own kind, they are often best kept as a single specimen. As a carnivore, its diet should consist of meaty foods like frozen bloodworms or brine shrimp, as well as high-quality sinking pellets. You should be aware that this fish is known to be a potential jumper, so a secure lid is a must. A truly interesting fish, but its specific needs and large size mean it is best suited for experienced aquarium keepers rather than beginners. It has a remarkably long lifespan, so be prepared for a long-term commitment.
