Santa dives to feed sharks in Budapest aquarium

The divers also installed a small Christmas tree at the bottom of the 1.4 million liter aquarium and decorated it with shells.

Deres said the tradition started a few years ago, though they usually knock over the tree quickly and then divers have to keep adjusting it.

The four sharks and fish also receive extra food for the holiday season.

The Christmas tree stays in the aquarium until the end of the season, keeping both fish and divers busy.
