This enigmatic creature combines striking appearance with fascinating behaviors, making it a prized addition to advanced freshwater tank setups. ## What Is a Ghost Knife Fish? The Ghost Knife Fish is not a true knife fish—despite its name—but belongs to the科 Apteronotidae, a family of charcoal-colored, transparent fish revered among tropical fishkeepers.
