A popular sunfish in Japan lost its appetite and banged on the side of its tank after the aquarium it lived in closed for renovations.

"When an aquarium in Japan closed to the public for restorations, the aquarium's beloved sunfish grew lonely without visitors and lost its appetite — until aquarium staff pasted cutouts with photos of human faces onto the tank," the video caption explains. That's right — they made people! Have you ever seen something so sweet?

An aquarium in Japan is getting creative when it comes to cheering up its fish! The Kaikyokan Aquarium in Shimonoseki, Japan, which is closed as it undergoes renovations, revealed in a post on X that its staff had to think out of the box to help one of its sunfish struggling with the change.
