My Naso Tang has gotten very dark gray on the left side of its face extending to the pectoral fin. The rest of the body looks fine. He is eating OK. No overt signs of distress. Just did a water change a week ago. All other fish fine. He has been in this tank a couple of years. No new fish added for < 1 month. He has been this way approx. 24hrs.
Any ideas or comments welcome.
