These guys have been in QT since the end of March. Started with Freshwater dips and Copper. Lately I have noticed flashing and heavy breathing, so I dosed Prazi as no spots were visible, expecting flukes. I did both treatments of Prazi and he is still flashing. No signs of ich or velvet. The only visible damage he hasanywhere is where he has rubbed on the PVC in QT while flashing. The Melanurus in there with him has attempted to clean him, as well, focusing on his gills. I have lowered salinity, working on getting to 1.009. Presently at 1.012 while RODI makes up some more. Will his flashing get worse/more desperate as the Hypo begins to take effect? He is dashing about like never before, and just laid practically on his side in front of the Melanurus... Pretty confident of the diagnosis. The Purple Tang is beginning to flash now, too. Is this normal? The Chevron, wrasses, clowns, and anthia are acting perfectly normal. I imagine that the flashing could be due to irritation from the flukes bursting and/or letting go. Anyone experience this before? Freshwater dip reveals NO flukes in bucket after being in hypo in tank all day.
