I seem to be encountering a similar issue with a newly acquired achilles tangs. The last one we recieved developed a very light spot on its belly area, very near the front, turning almost white. Other than this discoloration, no external issues seemed to be visual.
Upon recieving the second Tang, it seems to be developing this same discoloration and, although it has seemed to lessen, Im afraid there is a similar issue that will manifest itslef.
Any suggestions as to what this may be and whether it is relevant to the first loss?
All other fish in the system are doing great and I am running coppersafe at the recommended 5ml/4gals.
Thanks...
