Two weeks ago I purchased a flamehawk. When I got him home I noticed a small white dot above his eye. It has gotten larger very slowly following an outline above his eye. It looked hard until today, when I noticed the white area is larger and might be coming off, kind of fleshy looking. The fish is in quarintine with a longnose hawk. He is eating good and doesn't appear to be sick. Should I treat with antibiotics(which one?) or is it a virus. Thanks
