Random Question: Do Fish Yawn?

[Zoodiver]

Fish yawn to stretch the muscles in their jaw - same as us. Most fish will do it if you watch them long enough.

I know my datnoids are always doing it.

Particulary after they have eaten.

Ive only seen a few of my dempseys yawn but not my pleco...well i guess its becuase its mouth is on the ground.

So I guess they yawn for the same reason we do. wake up a bit and stretch their mouth

thae only thing i dont see yawn is my pleco lol

yea, can't say I have seen a pleco yawn, but I am sure they do something to stretch those muscles

I've seen most all of my fish do it before. Like others said though, my cichlids do it the most. Here's one of my clown loaches yawning...
