Had a racoon butterfly in qt for over 3 months with the same exact symptoms. Poor guy had every medicine/treatment thrown at him including CP, ttm, hypo, trifecta, copper, prazipro, GC, metroplex and formalin and still was not able to stop the flashing. Fresh water dips didn't show any flukes either. Unfortunately I wasn not able to cure it from whatever the issue was and lost him after 4 months in qt
Hope you have positive results!!
