Copper and foxface

[tapm]

Will a foxface tolerate copper? I am looking at getting one and will not put him into my tank w/o QT. I have used copper on all my fish so far but would do low salt if I had to. Do they do well in hypo or FW dips? Are these pretty hardy fish?
Thanks

foxfaces are very disease resistant just q.t it for 4 weeks and is it has no signs of disease of parasites you can add it to your display.
