Fish do not need air they need Oxygen which is a component of air. Nature always tries to balance things out so the surface of the water (meniscus) allows the transfer of gases. CO2 goes out into the air above and O is absorbed by the water. Plants also make Oxygen and use up Carbon dioxide. The fish have gills in which the membranes do the same thing as our lungs.
