fish can't close mouth

[prawn]

hello everyone,

i have a 70 litre long tank with a school of pacific blue eyes ( an Australian rainbow fish native to my area). I've had them for about 6 months. As i was looking at them today one opened its mouth as if he was yawning (they often do this) but his mouth never closed. i was wondering if this is a common issue and whether he had dislocated his jaw or if its a nerve issue.1/2 an hour later his mouth closed, which has dumbstruck me even more, what could have happened?

Thanks in advance,
Prawn

Dave, I think his user name is prawn


My fish had that problem once, it resolved by itself in a day or two. But I think @Mmathis also had a problem with this and hers, i think, the fish got a little pebble stuck in the mouth and she had to help it. I hope my memory's right.

Oh if thats the case I've had that problem too Nepen it took us Anethatizing the koi in question then with a pair of angled tweezers we removed a rather large pebble that the fish had swallowed then was unable to spit back out again .
After the pebble was removed we brought the koi back around again and that koi is with us to this very day .
