I think that most stars are bad news.
It seems we have two categories: Either they are carnivorous and thus not reef-safe, or they are "we haven't a friggin clue what it eats" (to try and sum up all the articles I've ever read about the topic).
Some of the "we don't know what it eats" stars do adapt to life in captivity but the numbers are pretty grim, probably like 1 in 10 or something like that. I did have a blue linckia that lived for about a year and a half. Is that a good run? I have no idea. But that guy was about one in about 5 or 6 stars that I've tried - the others never made it past a month or two.
