8-10” Redtail Catfish

8-10” Redtail Catfish – Majestic Freshwater Giant for Your Aquarium

The 8-10” Redtail Catfish is an impressive and sought-after species for freshwater aquarium enthusiasts looking to add a bold centerpiece fish. Known for its striking appearance and dynamic behavior, this catfish can grow into a true giant, making it a captivating addition to large aquariums.

Size and Growth Potential

While the current size ranges from 8 to 10 inches, Redtail Catfish are known to reach lengths of up to 4-5 feet in the wild. When kept in captivity, they can still grow to substantial sizes, often exceeding 3 feet. Because of this, prospective owners should be prepared for significant growth and ensure their tank can accommodate an adult specimen.

Temperament and Behavior

This species exhibits a relatively peaceful temperament compared to other large predatory fish but can display territorial behavior as it matures. They tend to be bottom dwellers and are most active during twilight hours. Understanding their temperament helps in selecting tank mates and creating a harmonious aquarium environment.

Tank Size Requirements

Due to their potential size and active nature, Redtail Catfish require a very large aquarium — ideally 500 gallons or more for adult specimens. A spacious tank provides adequate swimming room and reduces stress, essential for their health and longevity. Additionally, providing hiding spots and open swimming areas mimics their natural habitat and encourages natural behaviors.

Water Parameters for Optimal Health

• Temperature: 72-79°F (22-26°C)
• pH: 6.0-7.5
• Water Hardness: Soft to moderately hard (2-20 dGH)
• Filtration: Strong filtration and regular water changes are necessary due to the species’ high waste production.

Maintaining stable water conditions is critical to avoid stress and disease, especially given their size and activity level.

Diet and Feeding

Redtail Catfish are omnivorous with a preference for meaty foods. Their diet in captivity can include live or frozen fish, shrimp, earthworms, and high-quality sinking pellets formulated for carnivorous bottom dwellers. Feeding should be done once or twice daily, with care taken not to overfeed to maintain water quality.

Compatibility with Other Fish

Because of their size and predatory instincts, Redtail Catfish are best housed with similarly large, robust fish species that can coexist without risk of predation. Avoid keeping them with small or delicate fish that may become prey. Suitable tank mates include large cichlids, pacus, and other big catfish species.
