A small living world
between you and the noise.

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.

Not a loop.
A living presence.

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.
