I hear that once in awhile, I'm not sure what to make of that. It should have stopped by now. Typically, the fish will flash for a few days after the first treatment and then start up flashing again if you don't run the second treatment in time.Adding the quote so Jay see's my reply:
Hey Jay the Firefish and Gramma are still flashing at Day #9. Is that normal or should the flashing should have ceased by now?
Assuming you dosed for the correct volume, I would just go with the second treatment and see how it goes....
