I recently started working at the LFS a part time once in a while thing. A lot of the fish are coming down with a disease that I am not sure what it is. We tested the water today in all the tanks and they are all within norm ranges. The fish are all faded with this weird spots on them (not ich) they look like faded spots. I will try to get a picture tomorrow. Other then this weird color change they are all eating and seem fine. So far all the tangs have it and a clown trigger. These fish are not and have never been in the same tank. It is in 3 different tanks. This has all happened over the past week.
