If I switch to a small sensor camera - like a 1" sensor, I'll triple the depth of field at a given camera setting and the same focal length. Therefore, I can use a lower ISO to achieve the noise level I'm looking for.

Nope ... "duff science" I'm afraid.

Acceptable depth-of-field varies with sensor size.

If I take a "full-frame" lens and mount it on my APS-C (effectively half-frame) camera, the depth-of-field markings on the lens become "one stop out", that is to say, if I want "f/8 depth of field", as marked on the lens, I need to set the aperture to f/11.

As for photographing fish in a tank, I've done some in the past and don't remember any problems with flash disturbing the fish, though I do remember having to "try and try again" to get a result with no unwanted reflections. This was in the days of film, with no immediate gratification of instant preview, having to wait to get the film processed before I was sure I'd achieved what was wanted I have vague recollections of diffused flashguns on extension cables, but can't remember the details
