Danio with mouth locked open?

1 of our zebra danios appears to have it's mouth stuck open. What is this? How do you treat it? Currently, he appears to be a normal weight, but doesn't appear to be able to eat.

Mixed school of zebra danios (wild, leopard, blue, glofish) in a 55 gallon tank with rosy barbs, clown loachs and a small pleco.

Water tests normal; no one else in the tank appears to have issues. Tank has been up and running over a year, no recent additions.

Update:

definetly not a birth defect, showed up in last day or two.

nothing appears lodged in mouth, but since it's small and swimming its hard to tell!

Thanks for the help.

    How long has this happened?

    this can be a genetic birth deffect

    or

    a disease

    or

    "something lodged in the mouth, sores or ulcers in the mouth. "

    I have been looking for quite a while and I have found that

    depending on what it is the fish may die. BUT,

    One fish keeper had their fish's mouth open for awhie but it ended up closing.

    Im sorry if it sounds a little confusing...

    Hope your fishy is OK :)
