Is this lockjaw?

[mantisfan101]

I left for 2 days for a vacation and saw my female like this. She’s been hiding all the time and I saw her mouth open in a finny position. She hasn’t really eaten since and always seems to be hiding and she doesn’t seem to be able to fully close her mouth. Is this lockjaw and is there a chance she can survive?

Update- I think she’s a goner. She’s beginning to pinecone right now.

Remove her before she dies, so that other fish don't start nibbling on her body and catch it, in case its something infectious.
