Marine Aquarium 2.6 is a port of the Mac/PC version created years ago. I used to own them and presently own version 3.0 for my iMac so I am familiar with the quality of work by this company. In my opinion, this app is on par with their work on computer platforms considering the limitations of iPod Touch/iPhone. First off, the graphics using Retina 4 display is pretty good. The fish and the background objects in the tank standout very nice. If you are looking for an aquarium game that involves feeding and growing fish, this is not for you. If you are looking for a relaxing aquarium app with nice sound and good graphics, this is a good choice. The app could have some nice enhancements that would give it 5 stars in my opinion and I ask the authors to consider these. First, allowing some background music might be a plus. Second, having more control over fish selection would be nice as well. Third, and most important, having features that allow auto-zoom and auto panning would really benefit this app. I use it at work when I am writing my notes and I find it a pain to manually move the focus around in the tank. Otherwise, this is a good app and I look forward to any improvements (hopefully). A port of version 3.2 would be worth the money for me. Thanks.

As far as looks go, this app has amazing graphics. The fish look and move incredibly realistically and the coral decorations, bubbles and light-ripple effects are probably the best I've seen in any aquarium app, though I find that the bubble sound effects actually get on my nerves rather than soothe me; it's too fast and high-pitched. While Marine Aquarium looks great, its shortcomings are in its complete lack of features. Basically you just watch the fish and you can control the brightness of the background and foreground. There's no interaction with the fish and you can't choose which types you want in the tank as it randomly generates different fish everytime you open the app. The lack of tank customization is another thing. You're stuck with one coral reef and one gradient background and it can become boring after a while. There are far better aquarium simulations available in the app store, however, if you're just looking for a pretty scene to look at and you don't care about the camera following fish, feeding them or any of that, then this app certainly achieves it, all while looking incredibly gorgeous. Bottom line is: it's basically like a 3D fish screensaver (and maybe that's what the developers were going for). If you're looking for interaction and customization, keep searching; but if all you're after is a realistic fish scene, look no further.

I bought the original screensaver version of this app for my iMac years ago, and it's still the most realistic looking aquarium app I've ever seen. I love it, and am glad I found the iPad version.I don't mind the lack of interactivity or the fact that the objects in the tank aren't customizable - it's relaxing to me just watch the fish swim around, and the aquarium the developers have designed is very colorful and realistic.What I would like to see are two things:(1) When the "more than one of a single species of fish" is selected, it would be nice of each fish of a single species varied slightly in size. Though I don't know how the graphics engine for this app works, I would think this could be done by randomly scaling each fish model up or down within about a 10% range.(2) I would love to see more Atlantic/Caribbean fish, especially some of those native to the Florida Keys. How about a Sergeant Major, Rainbow Parrotfish, Queen Triggerfish or Bluehead Wrasse, just to name a few?

Aquarian Filters and oxygen bubblers make different sounds. It's controlled by the bubble size, the air pressure and water condition. I like higher frequency and faster bubble rates. Folks that subjective. I agree though, more backgrounds would be nice. More fish which also ties into being able to pick the fish you want but this is only a $1.99 app and for my money the quality of the images and the best looking fish I've seen, we definitely got our monies worth IMHO.
