[GovtCheese]

Its a long story, but I have to be brief, cause it is 10pm and I have to be at work at 3am....
I have just QT'd my remaining angels (majestic, chyrsyrus, plus a sohal tang, and a purple tang)... they all have lost color and appear to have some discoloration, white patches (not spots like ich) on their bodies...

I currently dosed the qt w/ the recommended amount of copper ( seachem's cupramin)

I ask, is there anything else I can do??? is there any other prodect out there that you can recommend???

I have lost over an asfur, bellus and a blueface angel over the last 4 days...

I know that there is more info that I need to provide, and I will, but if you can just give me some advice... anyone please!!

Do a FW dip and check for flukes. I'm assuming all your tank parameters are fine.
