Create and care for aquariums filled with fish that grow over real time, including while you are away. Feed them, clean their tanks, and collect the currency they produce; you can also freeze tanks when you need a break.
Find fish by hatching eggs, breeding, fishing, or trading with other players. Breed fish with different attributes and seek unusual variants as you fill out the fish collection book. Fishing can also turn up rare species and decorations.
Decorate multiple tanks with customizable layouts, then visit other players’ aquariums or meet them in fishing lobbies. Tiny Mode lets you keep a small aquarium on your desktop while you use other programs.
Players often enjoy the game as a calm, easy-to-check-in-on aquarium, and appreciate being able to keep it on a second screen. Reviews also highlight collecting many fish, experimenting with breeding and variants, decorating tanks, and fishing alone or with others. Some players find the routine repetitive over time, and reviews also raise concerns about limited-time events, the effort involved in earning shells, and occasional technical or interface problems.
