It sounds like you’re asking about the little fish story, and the direct answer is: the fish got caught in the mesh of a net.

Quick Scoop

In the version that appears in school-style Q&A sources, the fish is swimming one day and then gets trapped in a net. A similar wording also appears in an English-learning explanation that says the fish was caught while swimming with its friends.

What that means

  • The event is sudden.
  • The fish is no longer free in the sea.
  • The “one day” part is just the moment the problem happens.
