Should we use articles and determiners before a singular-count common noun all the time? Are there exceptions?

For example:

A teacher plays an important role. but why fish lives in water?

  • Why does a fish (singular) live in water? or Why do fish (plural) live in water? May 19, 2023 at 11:53
  • "Fish lives in water" is the sentence wrong? i mean live+s May 19, 2023 at 13:49
  • Yes, it's wrong (unless you have a pet goldfish called Fish!). May 19, 2023 at 16:00
