In My Aquarium, Wii owners can choose the fish that will live in their aquarium and what decorations they'll get to enjoy. Choose the glass color, lighting, background design, style of gravel, rocks, or plant life for the world the fish will inhabit, and mix and match different fish in up to 6 individual aquariums. Owner can even send aquariums to friends using WiiConnect24 if they also have My Aquarium.
