I have a Dalmatian Molly who was showing signs of ich last week (flashing, had a couple spots), and also had a white-ish path of fuzz on her head so I started treating with Seachem ParaGuard. It has been 5 days of treatment and the ich spots seem to have gone away, but the white fuzz patch seems to have gotten worse. She also appears to go stiff sometimes and seem to have some sort of seizure-like episode. How do I treat this?
