Ah, the poor things! Fish breathe by passing water over their gills, which are like fine, blood-filled combs that snatch the oxygen dissolved in the water. In air, those delicate gills collapse and stick together; they dry out and cannot pick up the oxygen, so the fish suffocates even with all this good air around us. I see it too often in my ponds after a heavy monsoon—if the water gets too muddy or bad, they come gasping to the surface, their gills struggling. You learn to read that gasp like a mother knows her child's cry.
