Custom tattoos may kill fish

Custom tattooed fish may be big sellers at markets, but an animal expert say it is a cruel and potentially lethal practice.

In Laitai Flower and Fish Market near the Lufthansa Center in Beijing, four of over 20 fish stores sell marine ornamental fish that are tattooed using laser guns with beautiful images in order to make them more attractive to customers.

"Many people just love these kind of fish, it gives them a unique visual impression," said Li Jing, the owner of a tattooed fish store at the market.
