Reefling: A Cozy Desktop Aquarium

The release date for Reefling: A Cozy Desktop Aquarium is July 22, 2026, on PC. Designed to run as a transparent window in the corner of your screen, this simulation allows you to manage a persistent fish tank that remains visible while you work or browse other applications.

The focus is on low-pressure collection rather than strict management, featuring over 150 pixel-art species that unlock gradually over several weeks of play. Because your fish cannot starve or die, the experience functions more like interactive wallpaper than a traditional game. You earn shells simply by keeping the window open, which you can then spend on coral decorations or new fish. It is a specialized tool for anyone who wants a living, reactive aesthetic upgrade to their desktop environment without the stress of maintenance. Buy this if you want a zero-stakes digital pet that stays out of the way of your actual work.
