What the heck is wrong with my Black Phantom Tetra?!

[Joey_Jojo]

Hi folks,

I'll do the whole introduction on my second post, but for now I'm concerned about my fish. I'll link a detailed video below. Basically, my poor tetra's face seems to be falling off! I'm not sure if it's disease, because this seems to have happened in a matter of hours. But if it's not disease, I'm at a loss. There are no "aggressive" species in the tank, and my parameters are all normal. 

Any help is appreciated 🙂

It looks like a broken jaw it probably swim in to something in the tank I don't think it will recover you might won't to think about euthanizeing him

Yeah I had a feeling he wouldn't be able to make it looking like that. Suffice to say he wasn't much interested in eating. But man... I really can't imagine that happening by just banging into something...

It's difficult to no for sure how it injured it's self they can get startled and swim into things I had a fish kill it's self by swiming into the glass it does happen
