...they only want to know the size of my air sacs
Wait, what!? It actually happens for real? :O
I thought those things only happened in the appropriate adult comix:

See, what you need to do is ensure these harassing landlubbers is sleeping with the fishes before their intended time.
Give them a good tailslap to make sure they get the point. Waterboarding, for those more resilient, also works.
A very easy and most definite "no!" vote from me. I too use to just swim happily down the botlane on occasion, giving a splash of heal here, a bubble of kindness there, not having a care in the world...but then there's always someone who insist on making ripples in my own, personal pond of tranquility.
And it is here you must rise up to them, and show them the true fury of the water. The waves of fate are not to be triffled with, and while such a destructive force is not to be taken lightly and must be treated with respect at all times, you must show them that not even the fish gamers will be used as everyone's bait.
