Construct a thriving aquarium by collecting diverse fish species while managing tank upkeep and earning currency for upgrades and decorations. The game combines light management tasks like feeding and cleaning with idle progression mechanics, letting you expand your collection passively. Best suited for players seeking a low-stress, meditative experience rather than challenging gameplay.

Patch Notes

Gameplay Fish death removed – Fish can no longer die from sickness. Sick fish stay sick until cured. Decor passive income – Decors now give passive gold while the game is open. Amount is based on the decor’s required level (e.g. level 3 = 3 gold/hour). Does not apply when the game is closed. Offline EXP limit – Offline EXP cap reduced from 30 days to 1 day. Fixes Fish EXP bug – Resolved an issue where fish sometimes did not gain EXP after loading the game. Fish EXP reset – Fixed a save/load race condition that could reset some fish to 0 EXP. Code cleanup – Removed an unused variable that triggered a compiler warning. UI & Localization Decor passive gold text – Each decor in the store now shows its hourly passive gold income. Translations – Added the passive gold text to all 23 supported languages. Technical Save system – Improved save/load order to avoid overwriting fish data with an empty list during loading. Load flow – Fish loading now waits for required managers before clearing and respawning fish.

Major Update

Breeding feature has been added to fish. When female fish are fully mature and there is a male fish of the same species, breeding buttons will now appear. You can breed once every 24 hours and get eggs of the same fish species. You must have at least one empty space in your aquarium for breeding. Each egg takes up 1 space in the aquarium.Now when you buy a fish, instead of a fish directly, an egg will drop into the aquarium and you will wait for the egg to hatch. The time will be slightly longer for higher level fish.Fish hatched from eggs will have a random gender. All your existing fish will remain male.If you experience problems with the save system, press the "reset game" button from the settings button. We don't expect this to happen, but we don't want any problems in your gameplay. If you experience a problem, this will be the best thing to do.Adult fish will now provide you with income. You can see this information when you click on a fish. Passive income only works while the game is open.We have made some changes to the fish breeding and earning system.If a fish goes hungry for 24 hours, it will get sick, and sick fish will die if not treated within 24 hours. This is not something you can see in starter fish because they grow quickly and growing fish don't get hungry. (This is how it is for now, but we may change it in the future. Large fish may get hungry.)Touch mode has been added. This causes your fish to flee. It doesn't negatively affect them for now. We added it for your enjoyment.
