About

You run an aquarium where fish grow and reproduce on their own while you sleep. Buy smaller species to breed, sell the adults for profit, and use earnings to upgrade tanks and infrastructure. Growth happens in real time so you return to new batches ready for harvest. The interface stays calm and simple with minimal micromanagement needed between check-ins. The slow progression feels satisfying as you track population numbers and profit margins. Customization options let you tweak tank layouts and species arrangements for visual appeal. Over 70 fish types exist with distinct appearances and values. Rarer variants only show up through breeding or random events which adds a light luck element to the planning. Player forums note the repetitive nature but praise the low stress loop for casual play sessions.
