ok, i like that approach better. he is the only other fish in a 120 gallon tank except for 3 anthias, and 3 wrasses, so he isnt scared and he should have a stress free environment. from the website with the chart-i think it is a fungus. the guy i ordered it from said it didnt have it when it left, so it must have developed in the last 24 hours. so maybe reefD is right.
