this question has been driving me crazy!!!!! could it be the same feeling we get when we get into water like what happens to a fishs body and organs?

Since they wouldn't be able to absorb oxygen I assume they would feel panic.

Likely vertigo. Their lateral lines, which sense electricity and pressure, are probably the equivalent of our ears in this aspect, allowing them to maintain balance. Further, without the swim bladder pulling them "up" there would be a further lack of direction.

I would guess that, as far as breathing goes, it would be like us sucking mostly hydrogen; thin and nowhere near enough oxygen flowing into the system.
