The disc offers viewers four choices of aquarium to view.  Each of these tanks are absolutely beautiful, with a wonderful mix of fish and invertebrates.  This is the type of aquarium I would love to have.  I'll I'm lacking is the time and money.   There are triggers and tangs, anemone and rays, and even a few eels.  The tanks are sparkling clean and the fish are very colorful.

Each tank has three different viewing methods.  "Full" has a stationary camera filming the entire tank and was my favorite view.  It fills the screen with the fish and coral and it almost looks like there's a top notch aquarium inside of your TV.  "Close-up" follows a fish around and shows details of the various tanks, and "Edited" mixed the two together.

The problem that I had with this is that each "Full" and "Close-up" views only lasts five minutes each.  That's it.  After it's finished the screen fades to black and then loops back to the beginning again, but it's still a very short look.  The "Edited" view last longer, about 15 minutes, but this was my least favorite view.  The changing from close-ups to a stationary view of the tank didn't work for me, as the transitions were a bit jarring and reminded viewers that they were just watching a recorded film.

There is an option on the main menu to run all of the tanks sequentially in a loop, and that was the nicest way to enjoy the disc.  Even then, the Full view only last 20 minutes, which is far too short.

There's also one tank that has a rather unpleasant scene.  A large fish attacks a small Fiddler Crab a couple of times; picking it up in its mouth and then letting it go.  Eventually another fish comes along and bites the crab's large claw off.  While this type of behavior is prevalent in nature, it might be upsetting for children and is rather unappealing to watch.

Aside from that, I enjoyed the disc and can see it playing well at an informal party or gathering, or for someone who just wants to have something going on in the background.

The 1.78:1 MPEG-4 AVC encoded 1080p image looks very good, but not quite as startling as I was hoping.  The colors are nice and bright and the detail is wonderful.  The pores in the coral are easy to make out and the stripes of the beautiful lionfish are clean and clear.  The lens that was used has a very shallow field of focus however, which makes background objects much too soft.  This also means that when a fish swims in front of another in the 'close-up' mode, it's out of focus which ruins the illusion.  Sometimes a fish will swim slightly out of focus too, causing it to look soft.  Another problem is the lighting.  In a few cases the light reflecting off the white gravel at the bottom of some tanks is a little too bright and washes out details.

Audio:

Viewers have four different audio tracks to choose from, all in DD 5.1 with the exception of the first, "Aquarium Bubbles", which is in stereo.  That track has the sounds of water running through a small stream.  It didn't fit the aquarium images at all, which don't have any moving water, and was my least favorite soundtrack.  "Relaxation" is slow electronic music with one note slowly bleeding into another and "Sea Space" is similar but a little more dynamic.  Finally there's "Classical Music" which featured some generic (to my untrained ears) soothing orchestral music.  I enjoyed this final option the most.

All of the audio selections sounded fine with a wide range and no distortion or noise.

Extras:

While not listed as such, there is a final tank, filled with several Nautilus, that is available only in the "Close-Up" view.

Final Thoughts:

This came really close to being a good disc but it doesn't quite make the mark.  The five minutes that each tank view runs is much too short, and when the fish swim out of focus, even when only for a minute ruins the effect.  I was also surprised that the included footage of a limb being ripped off of a crab.  That would have been fine in a nature documentary, but in a screen saver it's a turn off.  This would be a good rental.
