A: Well, I guess you will have to accept the fact that you may be boring LOL ;).
But seriously, this behavior is very common and pretty much all bettas do in deed do that. You asked if they are yawning: The answer is no. (don't be relieved just yet, it still doesn't prove that you are not boring after all LOL). I believe that the reason bettas do that is because of their labyrinth.

It is believed that because Bettas originally came from shallow stagnant waters, which contained little oxygen, Bettas had to adapt by developing a new organ, called a “Labyrinth”, which would allow them to get the oxygen they need to survive directly from the atmosphere, above the water’s surface.

The “Labyrinth” is an accessory respiratory organ, located in the gill chamber alongside and above the normal gills. It is composed of bony plates covered by a membrane through which flows venous blood. By gaseous exchange, passing through the labyrinth organ, the oxygen content is passed immediately into the blood stream, then the used air is expelled. Because only small amounts of air can be stored into the labyrinth, bettas must make frequent trips to the surface to replenish it. This is why you will see your betta regularly going back up to the surface of his bowl to take a gulp of air.

The labyrinth allows betta to survive in oxygen deprived environments, such as small bowls, and to also survive outside of water for what seems a long period of time. Bettas are sometimes found on the floor, having jumped out of their bowl, and after lying on the carpet for quite sometime, come right back to life when returned to their water. The labyrinth also allows us, breeders, to ship bettas in small amounts of water (just enough to cover their bodies) without suffering fatalities.



As you see, bettas are very special fish. Now in what way might the opening of a betta's mouth and gills for a second be beneficial to the labyrinth? I am not exactly sure. Perhaps it is a way for them to flush out something. Another thought that comes to mind is that bettas are bubble nesters and that maybe this "yawning" behavior may have something to do with this as well. If you have seen a betta blow a bubble nest you would notice that the mouth movements are very similar to that of the "yawning".

I think bettas yawn. Or at least I see Cinder open his mouth and kinda looks like hes pushing his gills out. I've always wondered why animals yawned...its slightly mysterious.

Ok so I looked up yawning on Wikipedia and found this quote:

"Similarly, Siamese fighting fish yawn only when they see a conspecific (same species) or their own mirror-image, and their yawn often accompanies aggressive attack."

I guess it's kind of like when a dog bares his teeth to show how big they are. A betta will open its mouth to show the other betta (or person I guess, because Cinder does it when he sees me!!) how big his mouth is.

Other theories suggest animals yawn to simply stretch muscles that otherwise wouldn't be stretched.

Wow really? That's why my betta keeps "yawning!" because he is in a divided tank so they see each other alot. Well he'll also just randomly do it when he's away from the other betta so I think there are different reasons.

I got the cutest picture of my betta "yawning" and edited it!

Lebron yawns a lot, he's all alone. I don't think other fish are the cause for yawns, I think that's flaring. lol It's normal for them to yawn, I even asked OFL. If they yawn excessively then there might be something caught in their gills or throat way.

Over hundreds of bettas die in their small, dirty cups each day. Only you can help them live. Research and then save them, today!

It just states the process of the labyrinth. It just has a theory on their "yawning". It really didn't prove anything.

We mean by the way it looks. I know they really aren't.
