So I've been fighting flukes in my QT with 3 BFF (Black Pyramid, Pearlscale, and Auriga). Did a 10 min FW dip on the BP and PS last night. A few came off the Pearlscale and a TON came off the BP. The Auriga had some growth under it's mouth so I started it with a 90 min Paragard dip that it seemed to handle very well. I followed that immediately with a 10 min FW dip and the fish died about an hour later. Is that a big no-no to go from a Paragard dip directly to a FW dip? QT is also on week 3 of Cupramine treatment for ich.
