The Shanghai Ocean Aquarium has put five red-lined torpedo barbs on display, the first time the fish has been exhibited to the public in China, officials said over the weekend.

The fish, on display in the aquarium's southeastern exhibition area, has a bright red line across its body, the most distinguishing characteristics of its appearance.

The torpedo bard, which is found in India, is difficult to keep in an artificial environment, as it needs strictly controlled water temperature and oxygen levels, aquarium officials said.

The fish are very "shy" and love to hide in the weeds and live in groups, officials said.
