Do fish yawn?

[Tycoon]

I see my betta "yawn" from time to time... I think he's getting bored and needs some company lol.

Yeah fish do yawn, I notice my fish doing it occasionally. I think its more of a stretching thing than a tired / bored thing.

 

[Tycoon]

I know, I was just kidding about the bored part

 

[nate da fishman]

yes my jack dempsey male does that a lot

I've seen our angel yawn,
I also noticed that bristlenose plecos can blink

I am sure someone has a more technical name for it, but I say yes.

ive seen my angel and platies yawn

plecos dont blink; they rapidly move their eyes in a way that it seems like they are though. corydoras do it also.

My o's do it all the time... i've seen my columbian sharks and monos do it aswell...

my ctenopomas do it all of the time. They are basically an African cousin of the betta, too. when they do it, they stretched their dorsal fins out alot, too. definitely seems like stretching

I say yes. I have seen several species of fish that appear to do this. Interesting.
