The goldfish is a kind of aquarium fish that developed from carp by humans, and it was born to be kept in a fish tank to be watched.
Modern people live in their own perceived world just like a bunch of goldfish that have no thoughts of their own and tend to follow others blindly. They are too concerned about the opinions of others to blind themselves. They are eager to get attention to be grandstanding. They are trapped in the aesthetic values of the public.
