Do fish just turnaround and say nope, not for me.

Answer 1

They don’t just get swept down with the current. As you might expect, the fish are pretty good swimmers, and they are able to resist the current quite well to stay in their little habitats. They also will gravitate toward areas where there is less current when they want to chill.
