Can fish sneeze?

Answer: Fish cannot sneeze; in order to sneeze you must be able to breathe, to breathe you have to have lungs and nasal passages. They don’t have lungs, they have oxygen transference in their gills. What the caller saw was probably the fish expelling a gust of water, in order to clean out their system. Fish have a small pocket of air called a swim bladder but they don’t have lungs because otherwise they would constantly float to the surface.
