Happy Aquarium is a social networking game created by Crowdstar. In it, players can decorate their own fish tank and fill it with a variety of different types of fish. The player needs to feed their fish and maintain the cleanliness of the tank to keep the fish happy. They can also teach the fish to perform tricks, and mate different types of fish together to get new, unique breeds. Happy Aquarium also allows players to invite friends to visit their tank and help them maintain it, and lets them visit the tanks populated by their friends. The game is free to play, but players can choose to purchase in-app items using real money.
