What am I dealing with?

I bought these fish about 3 weeks ago, and put them in a cycled QT tank. Then I started loosing fish every week. I medicated with prazipro and then cupramine. I'm not sure if this is viral or bacterial infection?

Post in fish treatment section for more replies but looks like Uronema to me

Probably Uronema from what I can see. If its not uronema it is a very virulent gram negative bacteria. I have dealt with both and unfortunately it is never pretty.

Thanks for the replies!

I guess uronema could make sense... I have had this qt set up for almost 2 years now, and I do recall having these conditions on a good amount of my new fish over the 2 years and they all ended up dying no matter what I did. First I thought these were all physical injuries from jumping or figthing, but it systematically keeps getting on my fish.
