I bought a blond Naso a week ago and I can not find anything that he will eat except the algea on the powerhead screens and there is not enough of that for him to survive. I have tried dried seaweed, flakes, pellets, live plants, frozen brine and mysis shrimp. No luck with any of them. I know he is hungry because he keeps picking at the powerheads and rocks but he just swims by everything else I feed him. Anyone have any suggestions for me?
