If human can't see air, doesn't that mean fish can't see

Yes, If human can see air, then it means that fishes too cannot see water.

Explanation:

We cannot directly see the air around us .We know that it is present around us by the interaction between objects. For Example if you wave your hand out of the car window you can feel the air resistance on your hand.

Fish don’t see water in the same way we don’t see air. They can observe the effects of water by the objects. So they can feel the water as they swim and it flushes through their gills to survive .
