Sorry for not being clearer. Flashing is when the fish seems to 'scratch an itch' by rubbing (usually its gills) up against something.
I would increase the feeding frequency to 3 times a day, if you can, and add vitamins (not fats) to the Cyclopeze.
Considering the answers, the fish is still infected. Altering the sp. gravity to see if its behavior changes is not recommended. As long as the fish is still eating, let its current behavior go on.
I'm assuming your specific gravity is 1.008 to 1.010 during this treatment. If the fish misses two or more of its regular feedings, raise the sp. gravity up by 0.002 sp. gravity units per day until you get to 1.016. When you raise it each time, raise it slowly over a few hours. If the behavior of the fish changes and it begins to eat again, stop increasing the specific gravity and slowly lower the specific gravity to the previous level before the eating began.
