Fish do not yawn, at least not the way we do. They do open their mouths sometimes, but that is typically to attract mates or deter aggressors. They do not breath in the same way we do, since they do not live in an environment of air. Water passes through gills, allowing the fish to absorb it.

Why is my fish gasping underwater?
When fish gasp at the surface, it generally follows that they are short of oxygen. Often this is due to other pollutants such as ammonia or nitrite interfering with healthy gill function in the same way that we might fight for breath in a smoky atmosphere or in the presence of noxious fumes.
Why do betta fish come up for air?
A fish may linger near the surface because he's trying to breathe more easily. Remember, fish breathe dissolved oxygen—not oxygen that is already combined in the H2O molecule. Naturally, these dissolved oxygen levels tend to be higher near the surface, where interaction between air and water takes place.
Do fishes fart?
Most fish do use air to inflate and deflate their bladder to maintain buoyancy which is expelled either through their mouth or gills which can be mistaken for a fart.

How do I fix low oxygen in my aquarium?
Increasing water movement is the quickest way to increase oxygen (O2) levels in a fish tank, as it allows more O2 to dissolve and carbon dioxide (CO2) to be released. This can be easily done using an air pump, performing large water changes, manually stirring the water, or placing a fan near the aquarium.
How do I get more oxygen in my fish tank?
Emergency Action. If your fish are gasping at the surface of the water, take emergency action to immediately increase the tank's oxygen: Perform a large water change (as much as 50 percent of the tank's volume). Then increase the water movement by adding a powerhead, airstones, or even an additional filter.
