The game allows players to manage a flock of fish in a virtual aquarium. Players collect and feed the fish, maintaining their health and happiness levels.
As players progress, the fish deficit can spread across other areas of the aquarium, requiring additional attention to balance the ecosystem. The ultimate objective is to create a harmonious environment where all fish thrive, by making smart decisions about feeding, removing debris, and other tasks.
