My Aquarium (Blue Oasis: Sakana no Iyashi Kuukan in Japan) is a WiiWare video game initially released in June of 2008. The game is a virtual pet simulator that allows the player to create and evolve their own aquarium and then send them to other players. Critically the game has been considered average, with IGN saying that it was basically a screensaver for your TV and literally had no gameplay (despite this, they "rewarded" the gameplay with a 5/10).
In all, the player can manage a total of six different tanks that contain a variety of fish. You'll be able to greatly customize the entire tank to your preference and, as formerly stated, send them to your friends if you wish. While the fish are the primary aspect of the game, you'll also be allowed to include various plants in your personal aquarium as well, not to mention the fact that you can change your background.
My Aquarium is one of the only games on the console (much less WiiWare) that takes information from the Forecast Channel and implements it into the game, changing the lighting and environment as the weather in your local area is altered.
Its sequel entitled My Aquarium 2 was released in Japan on August 3, 2010 and North America on August 9, 2010.
