Black Ghost Knifefish
The Black Ghost Knifefish is a member of the Apteronotidae family and the speckled knifefish group. It is considered a true bony fish. When properly cared for, the Black Ghost Knifefish can reach well over one foot in length. It possesses a weak electrical organ at the caudal peduncles which is used to locate food.
It requires a minimum of a 150 gallon tank with excellent filtration. It is generally timid and reclusive, preferring a fine-gravel-bottom aquarium with plenty of roots and rocks for hiding places, as well as subdued to dark lighting. To better appreciate this fish, many hobbyists will purchase a “ghost tube,” a clear plastic tube that facilitates viewing during the day. Once accustomed to its surroundings, the Black Ghost Knifefish can become incredibly tame.

My Black Ghost Knifefish has been in the tank for six months now. It’s very quiet and stays hidden most of the time. I use a ghost tube to watch it during the day. It’s calm and only comes out at night. The tank needs excellent filtration, which I’ve maintained carefully. A great choice for a peaceful, low-maintenance aquarium.

This fish is fascinating once it gets used to the tank. I started with a 150-gallon setup and added plenty of roots and rocks. It’s shy at first but becomes quite tame after a few weeks. I keep the lighting low and use a clear tube to observe it. It’s a unique addition to any aquarium.

After reading the care guide, I set up a 150-gallon tank with fine gravel and dark decor. The fish has adapted well and is now active at night. It doesn’t seem to stress easily and stays in hiding most of the time. The electrical sense helps it find food without much disturbance.
