Black Ghost Knife
Overview
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 is a fascinating addition to my aquarium. After setting up a 150-gallon tank with plenty of hiding spots and dark lighting, it settled in well. The fish is quiet and mostly stays hidden, which adds a peaceful atmosphere. I use a ghost tube to watch it during the day and find it very engaging.

I’ve had this fish for three months now. It’s shy at first but has become more active over time. The tank needs excellent filtration, and I’ve had to maintain water quality carefully. It enjoys the roots and rocks, and the dark lighting helps it feel secure.

This fish is unique and mesmerizing. The electrical organ helps it navigate in low light, which is a cool feature. I keep it in a large tank with fine gravel and plenty of hiding places. It’s not aggressive and stays mostly still, which makes it a great choice for a calm aquarium.
