I have a Clownfish in a QT. Its been in there going on week five. It has white salt grain like marks on his bottom fin also 1 spot on his body and 1 little bigger grain on his top fin. I tried to take pictures but they didn't show up on the pics. Today is day 10 treating with Cupramine daily test have shown that I had the copper at 0.5mg the entire time as per the directions. With 4 more days to go in treatment there is no sign of improvement and all of the spots are still there. The fish is active and eating well. Anyone have any suggestions on what could be going on? Thanks
