Black Ghost Knife Fish | 8-9 Inches | Single

The Black Ghost Knife Fish (8-9 inches) is an elegant, elongated fish known for its striking black coloration and unique body shape. It has a smooth, ribbon-like body with a long, flowing fin that runs along its underside, which it uses to glide gracefully through the water. This fish is nocturnal, becoming most active at night, and uses electrical fields to navigate and find food. It thrives in a well-maintained tank with plenty of hiding spots, warm water (75°F to 82°F), and a pH of 6.0 to 7.5. It prefers a diet of high-quality sinking pellets and live or frozen foods like worms and shrimp. The Black Ghost Knife Fish is a peaceful but somewhat territorial species, making it best suited for tanks with non-aggressive tank mates.

Body Shape: The Black Ghost Knife Fish at 8 to 9 inches has a more pronounced and mature version of its characteristic elongated, ribbon-like body. It maintains its sleek, streamlined form, with a smooth, scale-less surface that enhances its ghostly appearance.

Coloration: The coloration remains predominantly black, giving it a striking and dramatic look. As the fish grows, the black color may deepen and become more uniform. The glossy, dark body contrasts with the lighter-colored fin edges, accentuating its unique appearance.

Fins: The large, undulating fin runs along the lower part of the body, extending from the pectoral fins to the tail. This fin, which resembles a knife, becomes even more impressive and flowing as the fish matures, aiding in its graceful and fluid movement.

Movement: The Black Ghost Knife Fish uses its long, undulating fin to move in a wave-like fashion through the water. This motion is smooth and continuous, allowing the fish to glide elegantly and maneuver through its tank with ease.

Activity Level: As a nocturnal species, the Black Ghost Knife Fish is most active during the night. It is best observed after the aquarium lights are turned off, when it begins its foraging and exploring behaviors.

Electroreception: This fish utilizes electroreception to navigate and detect prey. It generates weak electrical fields and senses changes in these fields, which helps it locate food and navigate in low-light conditions.

Tank Requirements: An 8-9 inch Black Ghost Knife Fish requires a spacious aquarium with plenty of hiding spots and structures to mimic its natural habitat. Include elements such as driftwood, rocks, and plants to provide security and enrichment.

Water Conditions: Maintain a warm water environment with temperatures between 75°F and 82°F. The pH should be kept between 6.0 and 7.5. A soft substrate and gentle filtration are recommended, as the fish prefers low to moderate water flow to avoid stress.

Diet: The Black Ghost Knife Fish is carnivorous and should be provided with a varied diet to ensure its health. Offer high-quality sinking pellets, along with live or frozen foods such as worms, shrimp, and small fish. This diet should mimic its natural feeding habits and provide the necessary nutrients for growth and vitality.
