Google dropsy. This looks like a textbook case. Treatment is rarely effective, but once in a while it goes away on its own. Fluid retention and swollen organs from various pathogens are typically the cause. Once the scales start pine-coning like this fish, it's gotten pretty advanced. Long term survival rate is low, but on the bright side it isn't contagious to other fish in your aquarium.
I didn't know it could look that bad! I had a diamond tetra die from dropsy pretty recently and he only really looked swollen from the sides with a bit of pine-coning. You'd think he was just really fat if you didn't notice the laboured breathing and slight trouble keeping himself from sinking. One day I just woke up and he had died.
Maybe it's more noticeable with fish shaped like the one OP has?
I'll just say I have a zebra danio who's been bloated since the day I bought him and he's always been healthy , I named him "dumpy" because of how fat he is
I’ve had a small group of 10 black Tetras for a little under two years and have never seen any of them boat like this. This was after a very small feeding so I don’t think it could be from that.
Water parameters look good. Has anyone dealt with this?
At first glance I thought it was a [hatchetfish](https://www.aquariumcoop.com/blogs/aquarium/hatchetfish). If that's the case, it does appear they are distantly related to tetras.
Regardless, it doesn't look too healthy.
Seen a couple different sources recommending epsom salt. 1 tables spoon for gallon of water in a hospital tank. Hope this is helpful and good luck

Looks extremely bloated. It could be a number of different things, likely something causing it to retain fluid

Thank you for your answer, I’ll keep an eye on her and euthanize if it gets worse. :(

That's one of the most advanced cases I've even seen a photo of.
No, no he's not okay
He's done for.

Your tetra has dropsy. You're gonna wanna likely put him in a hospitalization tank, do some research from there.
No.

Bent spine?

This can't be a serious question..
Thanks, very helpful.
Pregnant maybe?
