The Iridescent Shark, also known as the Pangasius catfish, is a large freshwater fish that is native to Southeast Asia. Despite its name, it is not a true shark but rather a type of catfish. It can grow up to 4 feet (1.2 meters) in length and weigh over 40 pounds (18 kilograms).
The body of the Iridescent Shark is elongated and cylindrical, with a silver or grey coloration and a black dorsal fin. Its body is covered in tiny reflective scales, which give it a shimmering appearance. The Iridescent Shark is a popular fish in the aquarium trade due to its size and distinctive appearance, but it requires a large tank with plenty of swimming space and good filtration.
In the wild, Iridescent Sharks are migratory and live in large rivers and floodplains. They are omnivores and feed on a variety of foods, including small fish, insects, and plant matter. Due to overfishing and habitat destruction, wild populations of Iridescent Sharks have declined in recent years, and they are now considered a vulnerable species.
