Ok I have a clown and a goby that was in copper power at 2.25ppm for 14 days. I took them out and placed in another qt tank and now treating with prozi. All this is done as a preventative the fish never had any signs or symptoms of ich, brook, velvet or fluks. I was just trying to prevent thing from going into my display. I had a goby that didn't make it past the first day and it had the same thing im about to ask about that my new goby has. Around its head the goby has a area that is not as yellow as his body and is kinda pinkish. Is this some sort of disease or will this color up once he gets into my display with sand and becoms happy? I saw a post on uronema, im like "is this what my goby has"? I don't think it is
especially when I havent seen post about goby having it (not saying it can't happen though). Any input would be great, thanks. Oh and I was using a hannah check to measure copper.
