Craftrium

About the app.

Craftrium lets you build a virtual aquarium and leave it displayed in the room. Fish, plants, decorations, and unusual layouts can be combined without feeding schedules, water changes, or the physical limits of a real tank.

The arrangement affects which fish are likely to appear, turning decoration into a gentle collection game. Newly discovered species can be registered in an illustrated book, giving the calm display a reason to keep changing over time.

Immersive mode expands the aquarium into an underwater environment when a small window is not enough. Craftrium is a relaxing fit for collectors and decorators who want a living spatial object nearby rather than a game demanding constant attention.
