Kids feed the bottle-feeding koi fish with feeding bottles filled with fish food dissolved in water at Nui Coc Lake Tourist Area in Thai Nguyen Province, Vietnam (on January 31st).

Tourists flock to the water's edge to feed the fish in the bizarre fashion. These Koi carp are happier with a baby's bottle than a sprinkling of fish food. A baby's milk bottle is filled with fish food and put on the end of a stick. As soon as the fish see the rubber teat entering the water, they flock around the bottle in a battle to be the first for lunch.

Children were feed the bottle-feeding koi fish with feeding bottles as if the fish were babies. The feeding bottles aren't filled with milk but with fish food dissolved in water. The activity has become very popular among families with small children.
