So, what is the correct answer?

It’s 10.

But how has it been worked out?
Firstly, fish don’t drown, not in the conventional sense anyway.
Secondly, if they are all in a tank, the fish cannot swim out of it or escape.
And thirdly, if three have died, they would be floating at the top of the
tank.
Which means all 10 would still be in the tank.
