Happy Aquarium is a game you can play on Facebook. In the game you start out with one aquarium. In this game you take care of the fish in your aquarium.

The point of the game is to raise baby fish to adulthood in your aquarium and then release them to the ocean by selling them for Coins. Keep your tank clean and your fish well-fed to earn experience points so that you can level up. Leveling up allows you to have a bigger tank that can hold more baby fish. Decorate your tank and get your friends to rate it a thumbs up!

Besides the usual mechanics of buying and feeding fish, you can name your fishes, train them in an obstacle-course mini game, mate them to create new fish, and enjoy the simple pleasures of being an aquarium owner, like “cleaning” algae off the aquarium with the wave of your mouse cursor.
