The Pangasiidae contains Pangasianodon gigas (Giant Catfish), which can grow to over 6 1/2ft (2m) and weigh over 2401b (110kg). The genus Pangasius is the only one of the pangasiids encountered with any frequency in the hobby, with the Iridescent Shark being the species most often seen, either in its wild type or albino forms. Most specimens offered are juveniles, but they will soon grow into large fish. This is therefore a species that is suitable only for aquarists who can provide appropriate accommodations. It is widely bred commercially as a food fish as well as an ornamental one.
