I got this yellow tang last month and did a copper treatment, but a week after putting him in the display, he started to get a skin irritation behind his right gill. He was always out eating but now he hides all the time, and will dart out, pick at algae and go back behind the rocks. Does this look like flukes? I started noticing it about a week ago, and he is coming out a little more now, but he looks physically worse. After taking some photos today, it looks like there are some white ovals on him. Are these flukes? I’m going out of town tomorrow for about 5 days so I don’t want to move him to quarantine as I don’t have another ATO or auto feeder. I’ve got several corals and 2 clowns. Should I try treating with Prazipro in the display? Or do nothing till I get back?
the last two pictures are what he looked like when I first noticed it.
