i disagree, first off, i have a yellow tang and i hate it , he is always sick and always has that red bacteria infection so all i can do is stress to feed him seaweed selects everday, after this no more yellow tangs for me, i hate them. i have a clown trigger about 4.5 inches with 3 blue damsels and the clown doesnt even bother with them, my old niger did, but he could never catch them no way no way. they add a lot of colro to the tank, so i say get them but know that your yellow taNG will be a problem in my opinion.
