I have a royal gramma in qt that just started flashing 5 times in a row last night. It is going on it's 5th week of Cupramine at 0.5ppm (Salifert) and 3 Prazipro treatments. I haven't seen it flash since, but what are some things that would cause this behavior that Cupramine and Prazipro wouldn't treat? Kinda sucks because I was almost ready to put him into the display tank next week.
