[Emergency] Brooks claimed a clown, what should I do in DT?

[splix]

I noticed my clowns that usually host the nems have been just hanging out in the top corner of the tank for the past 2 days, which was definitely wierd. Last night I went to check on the tank before going to sleep and heard a little splashing. One of my black oscilaris clowns was basically white and you could tell had 2 feet in the grave. I caught him, looked up what it was and what I should do. Seems to me like brooks. I had salt water mixed and warmed so I fired up the QT real quick and caught him. I put him in the QT and he about instantly died. I then caught the rest of the clowns and put them into the QT. You could tell the other black one was coming down with it but I'm lucky I got to him in time.
There werent white spots and I dont think it's velvet based on pictures of it (sort of looks like powdered sugar a little with the white slime coat). The clown that died was basically a solid color just very white, like he lost all of his color. It happened crazy fast because just a few hours earlier he looked normal but was acting wierd.
I'm running cupramine in the QT and this morning all clowns are alive and seem ok.

Here is the delima. What do I do with the other fish in the DT? I would have to find a cheap large tank and set it up as a QT. I have 2 sizeable angels, moorish, couple wrasses, couple anthiases, and a handful of small fish (chromis and blue damsels).
Everyone in the DT seems ok, not acting wierd, eating, swimming, look fine on close inspection.

OF COURSE I get called out of town for the next 2 weeks so I have to do something today.

Is it worth going to craziness today and get them all in a 75+ gallon QT or wait and see in the DT (based on them all seeming fine).

If copper worked it most likely isn't Brooklynella you are dealing with.
Trichodina would be a possibility and fits the description.
Formalin treats both, which is why Trichodina is usually misdiagnosed as Brooklynella. Both have very similar symptoms.

I just looked at the other black clown that had it last night. He still has it and isnt looking so hot. He's alive though, for now.

I would discontinue the copper treatment and switch to giving the affected fish formalin baths followed by a tank transfer.

I cant find formalin around me. Still trying

It's hard to tell whats on the glass and whats on the fish in these pics. The only thing on the fish is the red spot on his gills. No white spots, thats all glass.

Found Formalin. Before I use it can anyone tell me if it looks like brooks or not?

 

[ThRoewer]

The pictures are not clear enough, but it looks like they have something on their fins which could also be bacterial.
A formalin dip won't hurt and I would do it in any case. Additionally you may want also treat them with antibiotics. I would try BiFuran.

Just did a formaline dip, prazi and cupramine are in the QT with them now.
The little black clown is acting much better this afternoon than he was this morning. The color spot on his gills isnt red anymore and now just looks like a discoloration.
