Can i use tap water and boil it for betta fish?

Betta's are a very strange type of fish. For most fish putting them into previously boiled water would kill them, boiling water removes the oxygen vital for life. However, Betta have a special organ that lets them breath atmospheric air. Which means every now and then bettas will go up to the surface to get air. So maybe there is a chance of a BETTA surviving since it would not rely on the air in the water.
