I don't have experience with that particular species, but I have successfully QT'ed several other species.
So far, all of mine have had ich, so first thing is cupramine. I use a very low dose, just enough that you can't really see it on the test. I think it comes to about 2-3 drops per gallon. The lasts for 6 weeks, with another two weeks without cupramine to confirm that the ich is gone.
For bacterial issues, which most of mine have also had (milky skin, red sores, etc etc) I've used FW dips and then Nitrofuracin Green Powder. I've been very happy with the results of this product. I've used it during copper, if need be, without issue.
I only do prazi after they are eating well, and all the other stuff is done with. Only exception... if flukes are obvious, and the fish is in major distress, I would prazi even if not eating well yet. Also, FW dips will alleviate immediate issue caused by flukes.
When I say FW dip, I mean like a good 10 minutes, BTW...not 2-3 minutes.
HTH.
