Platy's face has become disfigured

My blue Platy has recently changed in that her mouth has become diagonal at a funny angle. When you look at her front-on, she looks really odd. She was normal when I bought her about 5 months ago but now appears if she has had a stroke or something? Any ideas what has happened?

Has her behaviour and feeding habits changed in any way since this developed? It would be useful if you could post your water parameters, tank maintenance schedule and also a picture if at all possible.

No her behaviour has stayed the same and she is still just as eager for food as she was before! The other platies are all fine so I can't be doing anything drastically wrong, I wondered if it may have resulted from pregnancy as I have found a lot of Platy fry lately although I cannot be sure who the mother is.
