Thousands of goldfish are taking part in an art exhibition in Tokyo.
The third Art Aquarium exhibition kicked off this week. Japanese "art aquarist" Hidetomo Kimura uses 5,000 goldfish in 14 installations, made up of 70 aquariums.
It includes an 8m long centrepiece designed to represent the four seasons of Japan.
The exhibition turns into a music lounge in the evenings and at weekends, called Night Aquarium.
Art Aquarium runs until September 23 at Nihonbashi Mitsui Hall, in Tokyo.
You can check out some of the installations in the video below.
