- Elongated, blade-like body: The Black Ghost Knife has a long, thin body that resembles a knife. It can grow up to 18 inches in length.
- Black coloration: True to its name, the Black Ghost Knife is almost entirely black, with a faint silvery sheen on its underside.
- Lack of pectoral fins: This fish doesn’t have pectoral fins, which adds to its streamlined appearance.
- Long, flowing dorsal and anal fins: The Black Ghost Knife’s dorsal and anal fins are fused and extend the length of its body, giving it a ghostly appearance when it undulates.
- Electroreceptors: This fish has specialized organs called electroreceptors, which allow it to sense electrical fields in the water. This helps it navigate and locate prey in murky environments.

Sera gH Test
Makes it easy to monitor the total hardness
