The Shimonoseki City Aquarium in Japan's Yamaguchi Prefecture needed to undergo renovations, and temporarily closed to the public in December, 2024. Staff said the aquarium's sunfish lost his appetite after a week without guests. Their solution? Paste clothing and pictures of human faces to the wall of his tank, mimicking the hundreds of people who normally peer in on the fish each day. After putting up the fake visitors, aquarium workers say the highly social fish perked back up.
