Is there any chance the tank could have been contaminated with something? Something like air freshener or deodorant sprayed in the room, some perfume or hand cream or something else on your hands before putting them in the tank? Have seen someone lose fish like this, and it turned out to be their mother using windex to clean the tank glass, and the person was accidentally touching the glass then the water, without knowing about the chemical.
Dealing with aquarium fish disease is a fact of life in the aquarium hobby. Take the time to learn about the shimmies, or livebearer disease, to protect your fish.

Go to bed and get some sleep. Then tomorrow, we'll find out your GH and pH, whether from your post here or from your water company. It won't hurt to double check the actual numbers, but there's nothing more you can do tonight, so get some rest! If you're tired out tomorrow, you'll have a harder time taking care of your fish and reading up on different diseases.

@emeraldking @mbsqw1d any help here appreciated! The corkscrew swimming corylover describes, brings up results for Whirling Disease. This
person and posts on another forum, say that whirling disease can affect other types of aquarium fish, but the more scientific articles I've found refer specifically to the salmonid family, and claim it doesn't spread to fish of different species.

So my main suspects are the shimmies, some kind of contaminant, or possibly another kind of bacterial infection. Any thoughts?
I had to look at other websites selling it but they don't say much.
