I've been looking for a healthy powder blue tang for awhile and I finally found one that ate and showed no signs of disease, great color and everything. Well, I picked this guy up on Saturday, put him in the QT, and he started to show some white spotting Sunday morning.

I'm in the process of lowering the salinity to 1.009, but was wondering if I should treat with copper or some other chemical based treatment along with the hyposalinity. Any suggestions?
By the way, he's about 3" long, swims and eats healthily. I love this guy! And I hope me makes it through. TIA
