A pond can be healthy without aeration but at a lower productive rate (carrying capacity or standing stock). Aeration becomes more important as the pond ages or as fish #s/weight nears carrying capacity or as fertility increases due to fish size/growth, feeding pellets or fertilization or due to water quality constraints. While the pond probably can be managed well enough to "be fine" for a few years no one can be sure of what will happen as there are way too many variables.
