4-5” Giant Featherback Knife Fish ( Chitala Lopis )

4-5” Giant Featherback Knife Fish (Chitala Lopis) Care Guide

The Giant Featherback Knife Fish (Chitala Lopis) is a stunning freshwater species known for its unique elongated body and graceful swimming style. Typically reaching a size of 4 to 5 inches when purchased from Rob's Aquatics Fish Shop, these fish have the potential to grow significantly larger in the right environment, often exceeding 20 inches in captivity.

Size and Tank Requirements

While our specimens arrive at a manageable 4-5 inches, prospective owners should be aware that Giant Featherbacks require spacious tanks as they mature. A minimum tank size of 75 gallons is recommended to accommodate their active swimming behavior and growth. These fish prefer a long, well-planted aquarium with plenty of hiding places created by driftwood and smooth rocks.

Temperament and Compatibility

Chitala Lopis are generally peaceful but can be territorial, especially with smaller fish that may be mistaken for prey. Their predatory nature means they are best housed with larger, non-aggressive tank mates. Avoid keeping them with tiny or slow-moving fish to prevent stress or predation.

Water Parameters

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

Maintaining stable water conditions with low nitrate levels is essential for the health and longevity of Giant Featherbacks. Regular water changes and good filtration will help mimic their natural riverine habitat.

Diet and Feeding

As carnivorous fish, Giant Featherbacks thrive on a diet rich in protein. Offer a variety of live and frozen foods such as bloodworms, shrimp, small fish, and high-quality carnivore pellets. They may also accept sinking pellets formulated for predatory fish. Feeding should be done once or twice daily, ensuring they consume all food within a few minutes to avoid water quality issues.

What Makes the Giant Featherback Knife Fish Unique?

This species is admired for its distinctive knife-like body shape, which allows it to glide effortlessly through the water. Its large, feather-like dorsal fin undulates gracefully, providing a mesmerizing display. Additionally, the Giant Featherback has a mild electric organ used for navigation and communication, a fascinating trait among freshwater fish enthusiasts.

Potential buyers often wonder if this fish is suitable for home aquariums. While it requires some experience due to its size and care needs, the Giant Featherback Knife Fish can be a rewarding addition for hobbyists prepared to meet its requirements.
