Merydith or Humblefish: I'm getting a purple fire fish this Tuesday...is he scaleless...if no copper, what should I use in QT...also will Prazi pro harm inverts in the DT if I need it?Yes you can. You can do coppersafe with most fish... I've seen it done with angels and wrasse both with success, though these people took great care and had extensive experience with copper treatment and fish in general. If plenty of care is taken and the knowledge of what it looks like for a fish to be copper intolerant then you could try it on any fish with scales. It's a good idea to not treat any smooth skinned or scale-less fish like eels with any copper.
