Quick damsel death

[LBReefer]

So, this may be a user error issue, but u picked up 5 damsels yesterday and added them to my ongoing QT tank. I know rookie error, I restarted the clock on my qt process.

But I also think the shock of the already at max dose copper may have hastened these fish deaths.

I have not seen black splotches like these before.
