    Default Do your Dojos "yawn"?


    0 Not allowed!
    I notice, occasionally, when mine are sitting on the substrate, perfectly still, they occasionally gape their mouths open in what appears to be a bored yawn, then close their mouths again. They don't repeat it in rapid succession like a fish would if it was struggling for oxygen. I don't think they do it because of any lack of oxygen or bad water, they just seem to do this naturally. May have something to do with the way they take in air from the water? I've read that Dojos, when out of water, can survive for quite some time because of a special way they process air or because of some special air mechanism they have. Like they store it within them or something. I'll have to find that article, again.

    Not worried or anything, just am wondering if anyone else has seen their Dojos do this? I think it's cute. It really does look like they're bored or sleepy.

    i have read that the 'blowing up' is because they are sensitive to barometric pressure.asians used them for telling the specific of weather supposedly?

    I know the article said they rush around frenetically when the barometric pressure changes, but mentioned nothing about this yawning motion, which mine only do when they're laying still on the substrate. I've seen my Dojos swim around rapidly and a little crazily, sometimes. They also like to shoot like a rocket to the surface.

    Anyone else actually see theirs "yawn"?

    my girlfriend has dojos that we do see yawn from time to time. i have quite a few fish who "yawn" actually. not sure if there is a reason (like resetting the jaw, or relesing pressure somewhere or what), or if its just something they do.

    either way i do agree its cute to watch

    My Blue gourami occasionally yawns actually. Just opens her mouth, stretches her jaws wide then closes. Usually before I turn out her lights or right when I turn them on in the morning.

    My dwarf gourami has definitely yawned before, and I've noticed my parents' yoyo loaches doing the same. I couldn't believe it the first time I saw it, but now its happened a bunch of times.

    Many species do it (not just mammals either), so why not fish?

    On a side note, the wikipedia article on yawning is actually pretty interesting...
