Can someone identify what is on the tail of this white tail tang? I got him 4 days ago. He is in QT with two wrasses. I am hoping to add another fish before starting a course of medication but the earliest the 4th fish could be added is Thursday. Other than the blotches, the fish looks happy and healthy. I have copper, Prazi, Metro, and GC at the ready. Thank you.
The other spots are on the glass.
