here's some pictures, it actually got up right after i took them and started swimming, but i don't know how long that will last
nitrates less than 10, alkalinity around 9

Assuming it’s not a disease or a pest like Ick or Velvet. The only way I have saved fish in this kind of condition is to built something that holds their body in place and upright and then position them near to a direct moderat flow source so that flow is constantly going through their mouth and gills. It acts like a ventilator.
Within 24 hours about 30% of them recovered.
Good luck, things like egg crate tie straps and clothing for pins come in very handy.

Unfortunately I've never had any fish survive once they get to that point. Sorry I can't be of more help. Hopefully it maybe just ran into something and got a mild concussion.
