Desktop aquarium companion that keeps simulating while you work. It is built to live on your screen rather than to be played constantly, and the ecosystem keeps simulating in real time even when you are not actively playing. You feed your fish, keep the water in good shape and decorate the tank with more than 140 items that affect oxygen, happiness and the balance of the ecosystem. Fish breed with genetic variation. Heaven Machine made it for PC.
