  • 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.
