Padak -2012- Here

However, the moment Padak enters the tank, the film subverts every expectation. The aquarium is a microcosm of despair. It is ruled by a grizzled, one-eyed old flatfish (named Pyeon in Korean) who has survived for years by preaching a gospel of cynical, terrified compliance. The other fish—a neuroplastic clownfish, a panicking pufferfish, and a deteriorating starfish—have surrendered. They accept their fate: eating cheap pellets, growing fat, and waiting for the "Knife Day" when a customer picks them for hoe (raw fish dish).

A mackerel named lives in a cramped fish tank at a seaside restaurant. One day, a young, naive mackerel named Spotty is caught and thrown into the same tank. The older fish in the tank have long given up hope of escaping back to the sea — they have accepted their fate of being eventually caught and eaten. padak -2012-
