Well I placed him in a cup because there isn't much light in my sump plus he won't sit still.Most of the last fish that died(recently) all had this.I don't know if its a disease or it was brought on by the silicone.My tangs, butterfly,blue throat,fox face all had this.The other fish that died were fine they just stopped eating.I don't know if this pic helps.You see the skin is flaking.The fish is eating the other fish that died like this eventually got this all over the body.Its not ich its like the skin has something wrong with it.Peeling I don't know how to describe it.I am afraid that this fish will die also.I have learned my lesson I will get another tank and place any fish or corals in there first.I also won't rush out to buy more fish.
