Size and Appearance

Reaching lengths between 10 and 12 inches, the Giant Featherback Knifefish displays a sleek, knife-like body with a prominent dorsal fin that resembles a feather, which gives this species its common name.

Temperament and Behavior

This knifefish has a generally peaceful temperament but can show mild territorial behavior, especially when kept in smaller tanks or with other bottom-dwelling species. It is best described as moderately aggressive, so careful consideration of tankmates is essential to maintain harmony.

Tank Size and Environment

Due to their size and active nature, the Giant Featherback Knifefish requires a spacious aquarium. A minimum tank size of 75 gallons is recommended to provide ample swimming space and reduce territorial aggression. The tank should include plenty of hiding spots such as driftwood, caves, and dense vegetation to mimic their natural habitat and help reduce stress.

Water Parameters

• Temperature: 75°F - 82°F (24°C - 28°C)
• pH Level: 6.0 - 7.5
• Water Hardness: Soft to moderately hard (2 - 15 dGH)

Maintaining stable water conditions is crucial for the health and longevity of this species. Regular water changes and proper filtration will ensure optimal water quality.

Diet and Feeding

The Giant Featherback Knifefish is carnivorous and thrives on a diet consisting of live and frozen foods. Suitable options include bloodworms, brine shrimp, small crustaceans, and high-quality carnivorous pellets. They may occasionally accept small feeder fish, but a varied diet is best to meet nutritional needs.

Compatibility and Tankmates

When considering tankmates, choose species that are peaceful to semi-aggressive and can tolerate similar water parameters. Avoid very small fish that could be seen as prey or overly aggressive species that may stress the knifefish. Suitable companions include medium-sized cichlids, large tetras, and other robust community fish.
