Short description of Marine Aquarium 3 3.0: After years of development, SereneScreen Marine Aquarium 3 is finally available for download and purchase! This is a Beta-Test version, but your MA3 Key Code will not expire, and entitles you to download all updates through the final version. MA3 is not just an update to previous versions - the entire program has been re-written from the ground up as a full 3D environment, taking advantage of the increased capabilities of modern video cards.
