The fish hasgills that they use to filter from the water the oxygen they need to as you say "breath" ,so when you put them on land there gills are not working anymore by filtering the water for oxygen because there is no water it's as you know just air (oxygen) so there gills are still trying to work but there is no water to filter oxygen for them.

Why cant animals on land breathe under water and animals in the water cant breathe on land?
From what I know about chemical compunds, there is too much H (Hydrogen) in water for land animals to breathe as there is none in air, or close to it. Also, it doesn't include Argon or Nitrogen.For their counterpart, Water animals can not breathe air(Except for dolphins and lung fish) because they do not reach a sufficient amount of Hydrogen. That's my guess anyway.
