Pangasianodon hypophthalmus (Iridescent Shark, Пангасиус)

Iridescent Shark, Pangasius Catfish, Striped Catfish, Sutchi Catfish, акулий сом. They are schooling fish, and a group of these swimmers makes a delightful display. The name is derived from its juvenile coloring, a silvery iridescence with a couple dark stripes, and a body shape resembling that of a shark. As they reach their adult size, which can be up to a whooping 4 feet (130 cm) in length in the wild, their coloring becomes a uniform darker gray, often without the striping. Southeast Asian nations have been utilizing it as an important food fish for hundreds of years and it is also a popular aquarium fish. They are relatively hardy and are peaceful with other fish, as long as their tank mates are too big to swallow. Be cautious! The Pangasius Catfish have bad eyesight and they are a nervous fish that can be easily spooked. Don't tap on the glass or startle the fish as it is likely to injure itself in its mindless flight. They can get hysterical when frightened and dash madly around the aquarium. The Iridescent Shark is native to the Mekong basin, as well as the Chao Phraya River and Maeklong basin, chiefly in Thailand, Myanmar, Laos, and Vietnam. They have also been Introduced into other river basins for aquacultural purposes. Due to their size and habitat requirements, aquarists will need to be prepared to provide a large aquarium of 300 gallons or more once they reach adult size.
