PROGRAMHAPPY  I paid a couple of months ago. After installing the recent security update from Apple, the screen saver no longer works. A black screen appears, with a message stating that "Marine Aquarium 3 does not work with this version of Mac OS X." I need a working version for the latest version of OS x 10.6.2!  
(Version 3.0.1)

MJKPHOTO  I bought Marine Aquarium as part of a MacUpdate Bundle. I just upgraded to Snow Leopard and discovered that version 2.6 doesn't work (the program will launch and play, but the screen save is not compatible). Because I purchased through MacUpdate, the developer's site doesn't recognize my Key Code and therefore I'm not eligible to upgrade. Thus 1 Star Rating. Worst. Very disappointing.

G4JAY  Ok, so this thing looks really nice. BUT... they claim you can spread the tank across multiple screens. Not from the screensaver you can't! If you use the screen saver with dual monitors, it mirrors the tank. The separate app lets you drag the size of the tank between dual screens, but how is that useful as a screen saver? I use the screensaver NOT the app. Am I missing something here?

STEVEN GOODHEART  This update is gorgeous. On my 24 inch iMac Intel Duo Core, I don't get any of the rendering problems mentioned in a previous review.....I mean, if I look super-close, using a magnifying glass, I can see very, very slight anomalies on the edges of some objects, but I really don't see anything that takes away from my viewing pleasure.

I love the "pan" feature, and the new moving background objects, especially the Christmas Tree Worm and the antler corals.

I love that I can have up to 30 fish on screen a once...looks amazing on my big monitor. The integration with iTunes is way cool and works flawlessly.

I also own and love 3D Aquarium, but the detail and movement of the fish is definitely superior - sharp, crisp, realistic. I see many more artifacts with 3D than with Marine Aquarium, by the way.

Finally, have to say that this new version is so gorgeous is breath-taking. Friends who have looked at it are just blown away by the realism of the look and movement of the fish. This was an upgrade from 2.6 for me, and I think it's worth every penny.

5 stars for sure.

(Oh, and try running this as your desktop with something like Wallsaver. You won't be able to get any work done...you'll just want to watch your desktop!)

CHRISWAN  I have evaluate the app

I still see a lot of texturing minor problems, such as:

- 1-2 corals which in real world sways a lot has not animated yet

- a lot of black semi transparent polygons on edges of the corals, and moving corals

- a lot of unintentional blank gaps between corals (corals doesn't adjecent correctly)

- temporary missing textures on when fishes about to move away / onto the back of a coral

And there's no option to move the tank manually CMIIW

Overall I still thinks the predecessor is better than the current version

CARLOS-SZ  The new 3D tank is very polished.

One thing I really miss (specially for my kids): the ability to feed the fishes (F key in the PC version).

Once this feature is added I will also purchase a Mac license for sure.

ESPIRIDION  I love this screen saver. Out of the Aquarium screen savers it used to be my favorite, but I already paid for the screen saver and then paid for an upgrade. It looks as though some features from version 2.6 are gone in version 3.

I'm not giving them another $10, and I would not pay $20 for a regular version.

In contrast, the FULL version of 3D Desktop Aquarium is only $13 and I don't recall ever paying for an upgrade. I've had it probably since 2006. That's more reasonable, and they also have other screensavers which are cheaper. If you buy a bunch together, there are further discounts. It has a nice effect of the tank filling up with water.

I also have Aquazone, but it's not as good and it is buggy.

DANMARC  Had the pre 3.0 version loved it and when it stopped working thought I upgrade but no ...my bought license did not work for an upgrade on their website. So a mail to creators got me an answer "I had to upgrade through whoever you bought it from". Now correct me if I am wrong but you would think a software license is a software license but in this case no. Although a lovely screensaver I have gone of this way of handling customers. Just using a simple free one now (red pill - Matrix influenced. Shame though

MTCOBRA  My old 2.6 version of Marine Aquarium of course no longer works with my Snow Leopard Mac, so do I complain? Not at all. Actually, in TEST mode, old 2.6 works perfectly, and for as long as I care to sit there and watch it. Let's face it -- screen savers are no longer necessary, and they normally run between the time of inactivity and sleep -- the screen goes black. So, what do we need screen savers for? For watching the cool graphics, the fish swimming along in the tank. And, as mentioned before, 2.6 works in TEST mode, so I can watch the fish for free for as long as I want. When I want the screen to go black, I'll touch the power button.

ALL the old screen savers that aren't compatible with Snow Leopard still work in TEST mode, and if that's what you do with them (Watch), then enjoy, and forget paying for upgrades.

CHRISWAN  Can't upgrade using the SN and e-mail address acquired from 2007 MUPromo Bundle...
