Does she appear to be trying to get something out like something got stuck? Is the jaw just hanging there?

Tubificina means I feed like live worms. She ate so much, and she couldn't close her mouth. And my friend told me what she's out of her up& down jaws. I am not sure.
You're correct. I am not sure she just open mouth, that's all. I feed artemia today. I don't know she could eat or not. I am not sure the jaw just hanging or not too.

Your betta appears to be clamped with stress stripes and it's too blurry to see about the mouth..
