Diet
Red Tail Catfish are omnivorous and primarily feed on a variety of foods including fish, crustaceans, insects, and plant matter. They are opportunistic feeders and will consume almost anything they can fit into their mouths.
Average lifespan
Red Tail Catfish are long-lived and can live for 20 years or more.
Size
Red Tail Catfish are large freshwater fish. Adults commonly reach 1.1 to 1.4 meters (3.5 to 4.5 feet) in length, with rare individuals reported at up to 1.8 meters (6 feet).
Weight
Adult Red Tail Catfish typically weigh 20 to 45 kilograms (44 to 100 pounds), and exceptional individuals have been reported at up to 80 kilograms (176 pounds).
About
Red Tail Catfish are native to South America, particularly found in the Amazon and Orinoco river basins. They inhabit freshwater rivers, lakes, and flooded forests, preferring slow-moving or stagnant waters with plenty of cover.
Size and behavior
Red Tail Catfish are known for their distinctive red tail fins, which contrast sharply with their dark gray or black bodies. They are bottom-dwelling fish and are often found in deep pools or slow-moving sections of rivers. Red Tail Catfish are nocturnal feeders and are most active during the night.
Diet and nutrition
Red Tail Catfish feed mainly on fish and crabs, and during the flood season they also eat fruit that falls into the water. They are opportunistic predators that swallow their prey whole, using their long, sensitive barbels to find food in dark or murky water. As large predators, they help keep fish populations in balance.

Conservation status
The conservation status of Red Tail Catfish is currently of least concern. While they may face threats from habitat loss, pollution, and overfishing in some areas, they are still abundant in their native range. However, local populations may be affected by habitat degradation and overexploitation, especially in heavily fished areas.
Fun fact
Red Tail Catfish have ancient roots. Fossils of their genus, Phractocephalus, have been found in rocks in Venezuela and Brazil dating back more than 5 million years.
