Well, the Kole Tang forced my hand. He was laying on his side breathing heavily, covered in white spots (sure didn't look that bad yesterday and he acted normal).
I quickly set up an emergency qt tank. Only let the salt mix for an hour. Dosed it with copper.
He's in there now, but he likely will not make it.. too far gone.
At least now I have the QT set up and can possibly save my clowns, chromis, and coral beauty. I'm not going to put them in until tonight, possibly tomorrow.
Wish I would've done this sooner or been more agressive. Hindsight is 20/20 and it takes experience to make an expert, I guess.
