Black ich on Scopas Tang?

[MrsClooney32]

I have moved my Scopas Tang to the QT tank. Just did a couple minute freshwater did and I didn’t see anything fall off of him. Any ideas?

If it is turbellarians, black ich, the FW dip will kill most of them, but the black spots themselves will remain for sone time (think scar tissue).
