Do fishes need oxygen?

Do Aquariums Need Air Pumps?

Best Answer

Fish need oxygen too, but since they don t have lungs, they take oxygen from the water in which they live.

The oxygen in the water available to fish is called dissolved oxygen (oxygen that is dissolved in the water).

Fish use gills to take oxygen from water just as we use our lungs to take oxygen from the air.

Does deep breathing increase oxygen blood?
