If a fish breaths water, do fishes fart water?

People breath in air and fart out air. So if fishes breath water shouldn't they fart water too? If a fish farts air, where does the air come from?

    No, but its fun watching bubbles float up from their behind.

    There is dissolved oxygen in the water and they absorb it through their gills, which creates the air in which they fart from.

    It's fish -- not fishes. Why are you asking these stupid questions? Some fish come up for air, like betta fish. I agree with kswck2.

    Water is mostly oxygen. Over 88%.

    Fish manufacturer intestinal gas the same way people do except less of it because bacteria do not thrive in room temperature and cold water environments far less methane gas is produced in the digestive system of a fish. But occasionally a little bubble of methane gas will escape the digestive tract of a fish you won't even notice it.

    Fish breathe the oxygen contained within water
