Sometimes called the "king of fish," the giant barb has a storied history in its Southeast Asia range. In Vietnam, this distinctive, large-headed species is called cá ho. In Cambodia, the barb appears in ancient temple carvings at Angkor and has been named the national fish.

The giant barb is a river fish that often frequents deep pools but may move seasonally into canals or river floodplains. Juveniles are often seen in swamps or smaller river tributaries.

Though they've been known to reach 660 pounds (300 kilograms), specimens above 220 pounds (100 kilograms) have become exceptionally rare in recent years. These massive fish sustain their bulk on tiny plants such as phytoplankton as well as algae, seaweed, and, during periods of high water, the fruits of submerged terrestrial plants.
