Why my new fish breathes like this?

the first youtube link is replaced and the second one that I shared today works well here is the link

Agree with DrownedFishonFire that it’s a cichlid yawn. Sometimes they do that, completely normal, looks cool on the big guys.

DrownedFishonFire and Deadeye many thanks. I did not know that fishes also yawn

I guess yawning from fishes are not contagious, I did not yawn when I saw that

I’ve seen my puffers yawn. Wish I could have gotten a pic because it’s the cutest thing ever for a fish. They start to puff up a little while they do it.
