Fish yawn?

[TheRealAndyCook]

Now and then my JD "yawn" ...he unlocks his jaw and stretches it as big as he can...he is solo tho, so I don't think hes attempting to show off to anyone, unless hes trying to scare me away

How ever I just watched a comet do it. Whats this action called? I assume its just a thing they do from time to time?

Many people call it a yawn. Don't think there's a scientific term for it. But most fish do it from time to time, to stretch I guess.

Maybe they're just sleepy.
