Hello, my hippo tang is acting odd again he is scratching on his sides with slightly elevated breathing. Other than the scratches I don’t see much of a difference in his skin no white dots that really stand out other than near the abrasion. He is still swimming and eating normally he just has more damage than he normally has from going in and out of the rocks. My tank has always run super high phosphates and I am bringing them down with a gfo reactor could that be causing the irritation? I would think it would help him.
