If it looks like it is yawning then it could be a parasite, toxic water or something is stuck in the mouth. If it is just normal mouth opening every once in a while then it is fine.

It keeps water moving across the gills, which is how fish extract oxygen from water.
In other words, it's how they breathe.
Sometimes fish come to the surface and gasp for air. That's a sign the water doesn't have enough oxygen in it. A few plants can help.

Because fish don't have lungs they have gills and the are constantly moving their mouths to get water past their gills so they can get oxygen in their blood streams.

They are coming up for extra oxygen, and goldfish like to communicate no matter in a large, small or pond like fishtank.. they like to make popping sounds to call other fish. I am a goldfish wacko. I have a 100 gallon with about 10 HUGE goldfish, I grew from feeder fish.

all fish need to swallow water and let it flow through their gills, so there they can get the oxygen out of the water...
some people think their fish is singing, though....
