I have a smaller hippo tang that I've had for 6-7 months. He has a small mark on his face that doesn't have any pigment, along with a few small spots around it. I feed seaweed daily and feed brine shrimp & mysis every other day. What can I do to fix this? My tank has very low nitrates, as well as phosphates. My purple tangs and other fish look really healthy. I've heard these tangs are more susceptible to head and lateral line erosion than other tangs. Just want to know if others had this problem and if they had any luck fixing it. Thanks
