They suffocate. Fish are adapted to extract oxygen from water (through the gills), not directly from the air (which requires lungs).

they breath oxygen in the water and when they are out of the water there is no oxygen for them and they die, it's like holding your head underwater for a very long time, you die, same thing only reversed.

Because their gills can not absorb oxygen from the air, only from water (a liquid medium).
Our lungs can only absorb oxygen from air (a gaseous medium).

Because they have gills that filter O2 from the water.

They are designed to extract oxygen from water, we are designed to extract oxygen from air
