Lonely sunfish in Japan gets cardboard human friends

Staff members believe the sunfish stopped eating when the aquarium was temporarily closed because it was lonely.

The move was a "last resort" to solve the sunfish's health issues, which a staff member believed had stemmed from loneliness, the aquarium said on its X account earlier this month. After the aquarium shut for renovation in December, the sunfish stopped eating jellyfish and started rubbing its body against the tank, the Mainichi Shimbun reported on Monday. Mai Kato, a staff member, told Mainichi Shimbun that the sunfish, which arrived at the aquarium a year ago, had a "curious" personality and "would swim up to visitors when they approached the tank".
