sick yellow tang


New member
i put in my tang yesterday into my DT, and he was QT for 4 weeks. Today, under my stronger lights, i noticed he had a small cut down his face next to his gill. heres a pic, sorry for the poor resolution.

Hard to tell from the pic, is it a cut or discoloration? If it was not like that before going into the DT, did someone in there attack it? You may have to try to catch it and get it back to the QT for treatment if it does not get better. I would supplement its food in the meantime to boost its immune system.
