What the hell is wrong with nemo!!!
 

This morning when I checked on my tank my male nemo seem to have his mouth wide open and didnt close it once. I thought he was just being will but even till now its still not closed. That can't be normal been over 12 hrs. I fed them to see if he will close it to eat but he seems like he wants to eat n chase the food then does nth. I looked into his mouth n his throat looks like its swollen and not that big but mouth is fully open like locked jaw. How I fix him?

Do you have a 'nem in your system that could have burnt/stung his mouth ? Or another coral that could do the same ? Or a shrimp/crab ?

Go google "Lock Jaw"

There is a few different causes sorry man I don't know if there is very many successful cases of recovery?

What's a... Nemo?

Bingo.

Sometimes if they fight they will lock jaw mouth to mouth. Is it possible that they had a fight?

Yup lock jaw

He's fine now thank god. I think one of the frogspawn tenticles somehow went into his mouth n stung him? Or maybe a temp one day lock jaw who knows but his throat looked swollen what it happened. Was pretty
Funny n worrisome lol.
