The black ghost knifefish is a tropical fish belonging to the ghost knifefish family. They originate in freshwater habitats in South America where they range from Venezuela to the Paraguay–Paraná River, including the Amazon Basin. They are popular in aquaria. Black ghost knifefish are popular, but require large, long aquariums due to their growth potential (up to 20 inches). Black Ghost Knifefish prefer stable water with a temperature of 24–28°C (75–82°F) and a pH between 6.0 and 7.5, mirroring their South American native habitat. They are carnivorous and feed on insects, crustaceans, and small fish in the wild, so they should be offered a diet of meaty frozen foods, worms, and small feeder fish in an aquarium setting.
