my yellow tang, has areas of his bondy that seem to look like he was peeling. They have been that way for some time. Thought it would clear up as I moved him to a bigger tank (a year ago, previous tank was not the ideal place for a tang) But now he is in a 90 gallon FOWLER, he eats very well. He eats many meat based products that i put in the tank for Potters angel and flame hawk. I also add Green algae sheets for him and vegetarian options as well. I know this should be the main part of his diet. My water is good. He seems healthy, other than these areas. It just hasn't improved! I just started soaking foods in garlic. Any suggestions....Parasite? Fresh water dip? anything would be appreciated!!
