Aquarium
Build a tank and interact with its fish.
Choose fish, plants, and decorations and place them in an aquarium. Feed the fish, name them, and watch their behavior. Your tank is stored in this browser so you can return to the arrangement on the same device.

Returning to your tank
Browser storage

Tank log

Why use Aquarium?
Open Aquarium when this style of making or play feels closest to what you want.
It is meant to be understood quickly through direct interaction, with more depth appearing as you keep playing.
