Mine eats the same food, and on the same schedule as all the other tangs.....feed once a day. I alternate between frozen mysis, brine, and bloodworms. And (VERY IMPORTANT), I put in an algea sheet at least once a day, sometimes twice. I say "very important" because, although all tangs love it, my Naso gets overly excited about it. Sometimes he will back off of all the frozen stuff and just look at the glass, waiting on the algea sheet, as if he would prefer that.
