As Christmas approaches, a South Korean aquarium has created a performance featuring a school of sardines dancing along with Santa. Let's take a look.

A South Korean aquarium in Seoul has created a special performance to welcome Christmas, which is just around the corner.

As a holiday treat, "Santa Claus" made his appearance in the large tank where he fed and danced with more than 12,000 sardines.

[Oh Young-hwan, Diver, Coax Aquarium]:
"We were thinking about Christmas presents for our sardines and sea turtles living in the aquarium and we came up with this event that Santa Claus is giving the feed to them."

Schools of shiny silver sardines followed the feed in the Santa diver's hands, forming various shapes as they swan around the tank.

A group of school children and visitors gathered to watch the performance.

[Seo Jeong-won, Visitor]:
"It was a fantastic show. The sardines made beautiful movements and it was a joy to watch. I'm sure this will be a great memory for my daughter."

The aquarium also displayed a Christmas tree with lights powered by a tank of electric eels.

An aquarium official said that an electronic eel can produce a maximum 800-volt current while it hunts for food.
