Animals, fish and humans blunder onto a snake, and that's their main
objective.
To not be seen. Lunch comes their way...

The fish'd have to be pretty unlucky, though, not to be
quick enough to outwit a reptile.

I dunno, there's a difference between outwitting a reptile and being
faster
than the speed of a snake strike ... I don't think goldfish can do either!
