Anybody know what this is?

I noticed a few days ago that one of my Albino Tiger Barbs seemed to have a proplem with its jaw, It seemed to be hanging loose as if it had been pulled down.
I put it down to a little bit of fighting with the others but now i have seen the very same thing with one of my giant Danio's.

There is no other markings or ailments like mouth rot of anything like that.
The two fish in question have stopped eating so there is obviously something wrong. Thanks.

If the fish have stopped eating not a good sign at all, have the fish injured them selves, fighting, or do you think it is a desease, i'm sorry but i don't hold out much hope for them if they are not eating.

Could you post a picture?
I'm wondering if it could be something along the lines of mouthrot?
What do you think Wilder??

Don't think so sounds more like a dislocation, don't no if i spelt that right sorry.
