If you're 14 feet under water (1 atmosphere of pressure, and you rise to

18000 ft of air altitude change to achieve the same percentage. If you
are at the bottom of a 14 foot deep tank of water that gets lifted to
18000MSL, the pressure on your body is not reduced by 50% - not even
close to it.

You are overkilling this deeply on-topic discussion of the effects of
altitude on goldfish, Tony, so running away won't get you off the hook.

We are discussing tiny fishes, gold, that spend their lives in a
fishbowl which might be a foot deep. Going to altitude in a glider while
in a gallon baggy of water will not change their fate, no matter the
deeply felt concerns of sundry PETA-people.

Even now the hand-wringers are girding themselves for their next crusade
against those of us who enjoy the occasional salad.

Mein Gott! Can't you hear the olives screaming?
