Locals in south Vietnam call these unique creatures 'cannon fish' because of their ability to fire water precisely at their prey.

The filmer, who caught this at a farm in Can Tho Province, said: "They can shoot water at a distance of 2 metres with very high accuracy.

"Visitors to the fish breeding area will experience the ability of this fish by attaching their prey to the rope and placing it above the water tank."

This unusual footage was captured on June 28.
