One of the many giants of the River Safari, the Mekong giant catfish, moved into the soon-to-be-opened wildlife park's aquarium on Wednesday.

The herbivorous species, which is critically endangered, is one of the world's largest freshwater fish. It can grow up to 3 metres in length and nearly 300kg in weight.

The River Safari, Asia's first river-themed wildlife park, will feature animals which live in freshwater habitats. This includes the giant freshwater stingray.

This Mekong giant catfish was obtained from the only captive breeder in Thailand. These fish are found mainly in the lower Mekong River in Myanmar, Laos, Thailand, Cambodia and Vietnam.
