Answer 1

A fish can’t really get out of breath if it’s actively swimming. Fish breathe by pushing water through their gills and filtering out the oxygen, so a fish that is moving will generally find it easier to breathe. However, they can become physically tired if swimming for a long time, as they experience the same lactic acid buildup that humans do.
