Answer
NOT ENTIRELY SURE BUT IT SOUNDS LIKE A FUNGUS RATHER THAN ICH. TALK TO THE STORE WHERE YOU GOT HIM AND SEE IF THEY HAVE HAD ANY OUTBREAKS OF WHAT YOU ARE DESCRIBING. IF YOU GO TO MARDEL.COM THEY USUALLY HAVE A CHART OF FISH DISEASES, OR GO TO GOOGLE AND TYPE IN SALTWATER AQUARIUM FISH DISEASES. IF I DISCOVER WHAT I THINK IT IS I WIIL LET YOU KNOW. GERRY.
