Why does it look like my betta is yawning?
If your betta appears to be yawning and everything else about your pet’s behavior is normal, it’s more likely that he’s simply breathing at the water surface through his labyrinth organ, building a bubble nest, or anticipating food.
Why does my betta open his mouth when he sees me?

Why does my fish open and close its mouth?
Why only some fishes, all fishes constantly open and close their mouths for breathing. By this, they take water in the mouth and pass it over their gills so that the gill filaments and the closely nit blood capillaries on them absorb the dissolved oxygen from the water and in exchange give out the carbon dioxide.
Why do bettas gulp air?
As others have said, bettas are labyrinth fish, or Anabantoids, and gulp air to supply part of their oxygen needs. This is why they can survive in those tiny bowls they are sold in. In the wild, they live in areas which are periodically flooded, such as rice paddies.
How do I get more oxygen in my fish tank?
The best way to increase oxygen is to increase the surface area of the aquarium. Increase Surface agitation or water movement on the surface. This allows more oxygen to dissolve and more carbon dioxide to escape. You can also add a source of fresh oxygen by installing an air pump.
Is my betta fish watching me?
Yep! They do, but it’s not what you think. Fish quickly learn to associate you with food. When they see you, they’ll come to the front of the tank and watch, anticipating that you’re going to feed them.

How do I know if my fish tank has enough oxygen?
The most telling sign that your fish need more oxygen is if you see them gasping at the surface — they will also tend to hang out back by the filter output. This area of your tank tends to possess the highest oxygen concentration as it is near the most disturbed surface.
