Starfish scientists who are also in the hobby theorize that it's salinity or ammonia shock from being collected / bagged / shipped. The orange ones seem to get to us faster than the purple or blue, so likely live longer. However, stomach content analysis of many species show bryzoans, hydroids, bacterial films, and sponges. So unless you have a really big, really well established tank with a diverse microfauna, they'll likely eventually starve.
