Dream Aquarium Screensaver is one of the most realistic desktop aquariums on the market, towering head and feet above the competition.
The developer of Dream Aquarium Screensaver calls it a 'next-generation' aquarium screensaver but doesn't explain what they've done to make it so. Whatever it is, the level of realism in terms of graphics, movement and stunningly bright colors is impressive. The swimming actions of the fish are particularly realistic as they nibble bits of food, dart in and out of coral and even chase each other.
The details in Dream Aquarium Screensaver even stretch to moving eyes, gills and mouth and different refractions of light as they hit the water. There aren't many options, although Dream Aquarium Screensaver will at least allow you to display the fishtank in widescreen format and even over multiple monitors if you wish.
Unfortunately, the Dream Aquarium Screensaver trial only features two different species of fish but if you upgrade, you get 16. Note that you'll also be plagued by the odd pop-up window using the demo version.
For pure realism, Dream Aquarium Screensaver deserves full marks but you'd have to upgrade to the full version to do it justice.
