Iridescent Shark Catfish Pangasianodon hypophthalmus

The Iridescent Shark Catfish, also called the Sutchi Catfish, is native to main rivers of the Chao Phraya and Mekong basins in Indochina. They can grow to 1.3 metres long.

Juveniles of the Iridescent are shiny with a lateral stripe but adults are brown or grey. Like the other giant catfishes of the region, it is endangered, through over-fishing and through construction of dams since the fish migrate upstream in the wet season to spawn.

An albino variant of the Iridescent is often bred in captivity.
