Not tail rot ... it is the only fish effected and have them doing the same thing at other locations. But only the yellow and purple tangs. Sometimes it does seem to show a deterioration of the slime coating and perhaps scales around the lateral line. Don't believe it is from tank mates as it does not erode with sharp edges. All the deterioration looks smooth, like it was burned off. It also does not grow back. I have seen this progress until the fish looks like it has a triggerfish dorsal (just first couple rigid rays remain)
