Hi all so after losing my original fish due to whitespot. I started again and brought a yellow tang, foxface and flame angel for my 40 gal qt tank. All have eaten like pigs since day 1. The flame would peck at bits even at day 1 of no cu. Cu levels have been at 2.5ppm copper power now for 11 days. No ammonia. Salin 1.024. Today the flame angel died. No sign of external parasites. Is it the copper thats done it or chances are interal parasite?
