An addictive yet relaxing Facebook application where you can tend an aquarium and raise your own pet fish. You can customize your tank with scenery and items from a virtual store, and earn gold by visiting friends' tanks and selling your adult fish for a profit. As you level up you can buy more fish, and more things become available as decorations.
