We were a little disappointed with the look of the fish in 3D Sea Aquarium. Their movements are fairly realistic, but they still look like they came from a video game. The scenery is also kind of cartoonish and the lighting changes colors, making it look even more like a cartoon.

The thing that we did like about 3D Sea Aquarium is the interactivity. You are able to feed the fish and watch them dart around the screen. There is also an option to "tickle" the fish for further interaction.

This program also has some great customization options in the menu screen. There are 10 fish to choose from, but another downfall of the program is that you can only have ten fish onscreen at a time. 

3D Sea Aquarium is priced to sell, but you might want to consider another aquarium screensaver if you're looking for more realistic enjoyment.
