I let me auriga butterfly slip through qt without seeing any gill fluke symptoms. Well now I'm pretty sure he has them. His gills open farther than normal, but the last 2 days I noticed he started scratching his head, he's never done this before, only twitch. I'm on day 4 of prazipro and I figured he wouldn't be scratching by now, but does this mean the meds are not working, or should I just keep on going? I overdosed prazi too (on purpose, I read of people doing it with no problem). Not sure what to do. I do have paraguard I could try, But I'm super hesitant to dose that in a display. Any advice is appreciated!
