DannyB, I have a naso tang and worried about what you are worrying about right now, when I first got him. He would only eat nori and sometimes seaweed selects, so I was worried he would not get all the vitamins and nutrition. And then I remembered, tangs eat algae and seaweed all day long in the wild and only rarely eat meats. So don't worry about it. My naso eats nori and seaweed selects almost exclusively, and occasionally will eat frozen brine shrimp, but thats it. And thats all he needs. Anybody that tells you a tang NEEDS other food than algae or seaweed doesn't know what their talking about. In the wild tangs eat other meaty things occasionally, but the main bulk of their diet is greens. Just keep the nori and seaweed selects coming and your naso will be a hog in no time. Goodluck, Jollygreen
