All the public aquariums I've been to don't allow flash, it freaks the fish out or something.
In fact, I was once told to turn off the focus light on the camera as well. So it was ISO a million, hand-held, no focus light and no flash. Quality shots, as you can imagine. |

| I made a spoffle for taking photos at a public aquarium. That is, a bit of black foam board with a hole slightly bigger than the lens diameter. Still have to handhold the camera, but you can hold it close to the glass, and it cuts out reflections like exit signs and whatnot. |

| how big is the piece of foam board? |

| I shoot with a .35mm f/1.8 at aquariums w/my D300s, like the previous poster said I get right on the glass so there is no glare. Really the only thing that would make the images vastly better in my case would be an FX sensor so I could bump up the shutter speed and not worry about ISO so much for noise prevention. Being able to go with a smaller aperture setting for a little more DOF would be nice if I had an FX, but currently if I want low ISO to prevent noise I really make use of that f/1.8. |

It doesn't have to be very big. I think mine's about than 20X30 centimetres (or it might be A4 size), about 1cm thick. (I'd be able to tell you precisely if I could remember where I put it ;-Þ).

What you're dealing with here is distortion caused by shooting through glass at an angle. I recognized that soft, wobbly look immediately. The more of an angle you shoot, the more the internal reflections and variations of the thickness of the glass cause these sorts of artifacts. The fish tank itself is acting like a terrible lens. Water moving behind glass won't cause this unless there's WAY more of a temperature differential than a delicate saltwater tank could handle.
Why am I so confident?
That's why! ;)

Oh and I never use a tripod, usually shoot at relatively small apertures (~F16), and almost always rely on a lot of indirect flash/selective lighting to get the look I want. But just keep that camera perpendicular to the glass and you're well on the way to fixing the problem.
I love shooting fish tanks. :)
Yes I do.
