New Features
Background Colors (Day/Night) - The biggest change in Marine Aquarium 3.1 is the addition of a user interface for changing the background colors. Up to 6 sets of background colors are allowed, and you have total control over all of them. You set a timer for each color group to determine how long that set will be displayed before fading to the next.
Clock/Calendar Etching and Custom Colors - Users can now choose the clock/calendar colors on the crystal (and the appearance has been improved). They can also now choose an etched look.
Fading Logos - Many fans have been suggesting that the user-definable logos displayed on the crystal should fade smoothly to the next, instead of an abrupt transition. This has been added to v3.1.
Limit Frame Rate - The Limit Frame Rate setting has returned in Marine Aquarium 3.1, replacing the somewhat confusing Sleep adjustment.
Music Playlist - Numerous minor bugs have been fixed in the music playlist feature.
Some of these improvements have necessitated changes in keyboard shortcuts. To see a list of the updated keyboard shortcuts, press the SPACE bar and choose About.
