The opposite of a fish is a gun. A red herring is a type of plot device or storytelling principle in which facts are introduced into a story that are intentionally designed to mislead the audience. An example of this is when you see some sort of clue that ends up having no merit to it in your favorite murder mystery. The opposite of a red herring is something known as Chekhov's Gun. It is attributed to Russian playwright Anton Chekhov, in which he famously said, "If there is a gun hanging on the wall in the first act, it must fire in the last." This is to make sure that no unnecessary details are intentionally put into a story. For example, a red herring would not be unnecessary as its purpose is to detract the audience's attention from the main plotline. But for other details, such as, say, the main villain puts a knife in his boot for later on, that the storyline is concise and actually make sense, and also to make sure that the audience's expectations are met so that when later plot twists come about, they feel like they were actually natural as opposed to coming out of nowhere, and the audience can have that sweet moment of realization. Like the shake, for example, it was an example of Chekhov's Gun, not a red herring.
