Are Pipefish Sensitive to Copper?

[Kengar]

Despite religiously quarantining all new fish, I have ich in my system. (I suspect it was on the damsels and chromises I recently added, but that I could not see it on them when they were in QT.) I intend to pull all fish from display, leave it fallow for eight weaks, and treat with copper in a treatment tank.

Question: are pipefish (banded pipefish, in particular) sensitive to copper? (I use Seachem cupramine.)

Thanks.
