Morphology
different + kettle + of + fish
The meaning 'a situation or subject that is completely different' cannot be predicted from the literal parts 'different' + 'kettle' + 'fish' because 'kettle of fish' functions as an idiomatic unit whose relation to 'a different matter' is arbitrary. A B1 learner who knows the individual words would therefore be unlikely to infer the idiomatic sense without prior exposure, and similar metaphors are not universally shared across languages.
Etymology
The idiom different kettle of fish may come from a simple picture of cooking fish in a kettle: a different kettle of fish meant a different batch with its own issues. So it now means 'a situation that is completely different'.
