There is not enough Oxygen in the air for the fish to breath. Water has just the right amount of air (O2) that the fish need and in the right proportions. Fish breath in water with gills. Water is capable to holding within it a very large amount of Oxygen. So it is super-concentrated. But the O2 in our air is far less concentrated then in water, so the fish try to gulp the air through and into their gills, but the gills cannot easily find or absorb the O2 from the regular, unpressurized air.
