Hey, I am very new to this saltwater fish and reef thing and I have reached the end of my rope. I love it, but I want to quit. I have treated my tank for ick, but my fish keep dying. 2 pecula clowns and 1 damsel, my second damsel is on his way out. They show symptoms of dorpsy, cotton mouth, wasting disease, and possibly velvet. I don't know if all or any are for saltwater, but bottom line is I need help. The fish have all had heavy breathing, stay near the bottom corner of the tank, easily startled, a white powder like dust on skin and fins, faded color, and loss of appitite, but what ever they have didn't have any effect on my shrimp. please help!!!
