A calm, low-effort desktop companion where you passively watch fish swim and grow while you work.

What players say

Players are split on this idle fish game. Some enjoy it as a cute desktop companion while watching other content, but many criticize the lack of tutorials, no breeding mechanics, and limited fish variety. The window cannot be resized and takes over the full desktop, causing problems for Linux users.
