Aurelia
Opal color and calm, measured movement.
Living 3D aquarium for Windows
A calm underwater world that lives beside your work. Feed expressive fish, discover natural behavior and grow a collection worth coming back to.
More than decoration
Desktop Aquarium is designed to be noticed, not managed. Fish explore, feed and move through real depth while you work, study or take a quiet break.

Keep it compact beside your apps or let the water fill the desktop in borderless mode.
Built for quiet focus
Responsive behavior
Drop food and watch fish notice it, approach from different depths and compete for a bite. Leave them alone and they explore the habitat at their own pace.
