water is a good conductor of sound compared to air, or in other words is a better medium for propagation, which means that the speed of sound in water is faster than in air. So the fish will not here it louder but at the same intensity as we hear it.

say what? have you ever tried to yell in a swimming pool? water is a TERRIBLE conductor of sound as compared to air......
water has density (the more the salinity, the greater the density), which prevents sound waves from propagating....where as air has basically no density..

Water is a much better conductor of sound than air but the sound waves in the fish tank cannot be greater than in the air surrounding the tank, so no, the fish wouldn't 'hear' the sound louder.
This is, of course, neglecting other factors, such as sensitivity of fish to sound, mode of detection of sound by fish (as far as I know, they 'feel' sound rather than 'hear' it), and transmissibility of sound by the glass tank itself, etc..

Another airport with fish is SRQ.

Yeah, because human vocal cords, which are designed to make noise in air, can't make the same noise underwater, that must mean water can't conduct sound.
Ever tapped a watch on a handrail in the pool? Try it sometime. You can hear it all over the pool underwater. Above the water, you can barely hear it at the other end of the pool. Of course that also has something to do with the ambient noise of the air.
But, back on topic, water doesn't conduct sound from the air very well. Yelling above the surface would barely be heard below. As a swimmer, I know this quite well. You tend to only hear the cheers of a race when your head is above the water. As soon as you dip under, you only hear the sound of swimming, and faint other noises.
So, no, the airport noise does not likely disturb the fish. But kids tapping on the glass does.
Of all the things to worry about... the Wookie has no pants.

Live fish must not mind it too much. America West used to carry live fish as cargo to pet stores here in Columbus. I remember unloading several dozen boxes of live fish off numerous A320s coming from LAX, PHX, and LAS while I was there. I think the only time they were really bothered was when they arrived in CMH during the winter.
