The Black Ghost Knifefish, also known as the Apteronotus albifrons, is a fascinating and unique freshwater fish species that is native to South America. These fish are known for their long and sleek black bodies and ghostly white stripe along their undersides.


These fish require a large aquarium of at least 100 gallons with plenty of swimming space and hiding spots such as caves and plants. They are a nocturnal species and are most active at night, so it's important to provide low light conditions to encourage natural behavior. They are best kept in a species-only aquarium as they can be aggressive towards other fish species.


Black Ghost Knifefish are moderately difficult to care for and are best suited for experienced fishkeepers. They require high water quality with excellent filtration and regular water changes. These fish are sensitive to changes in water conditions, so it's important to keep water parameters stable.


They are carnivorous and will feed on a variety of live and frozen foods such as worms, shrimp, and small fish. A varied diet will help ensure they receive all the necessary nutrients for optimal health and coloration.


Water Parameters:

  • pH: 6.5-7.5
  • gH: 5-12
  • kH: 2-8
  • TDS: 100-300
