Black Ghost Knife fish are tropical freshwater fish from South America. These are nocturnal fish that are most active at night and rest during the day.
As they are most active at night, their eyesight is not well developed, so they hunt and communicate through an electric field.
They are quite shy and not very social preferring their own company – they can become quite aggressive if kept with other Knifefish. After they settle down in the new environment, they will come out from their hiding place during the night and swim mostly near the substrate or foliage and plants.
