My 55" and Two 21" Tanks.

Yep, I measured by inches, and not gallons, as these are digital aquariums. Thought I'd share with you all, because this program is really cool, and worth every penny!
It's actually just a screen saver for your PC/Laptops, but I hooked my media server PC to my 55" TV and two 21" monitors, and set up three separate aquariums!

Dream Aquarium is the name of the software, if you do a google search for it, you should be able to find the website easily, and it's pretty affordable. There's also a free trial version that has a good number of features on it. Another cool feature is that you can have one tank span across multiple monitors, or have each monitor have it's own tank (as shown in my video). There's also a good selection of fish to choose from.

As of now, there's only three "3D" tanks, that are available, but you can also set up your own "wallpapers" as tanks. I use this screen saver on all my PCs and laptops
