It's unfortunate but most stars, any of the non-predatory ones, are a real mystery as to what is their real diet. Some may adapt, but some (if not most) will not and thus won't live out full lives in captivity. So usually the advice is something safe and along the lines of recommending a large tank with a large amount of live rock, but it's really all about "hedging your bets" -- i.e., hoping that there will be enough diversity that whatever it is that they're after is there in sustainable numbers.
For the most part, stars are just poor survivors. Some do make it but they seem to be a minority.
