Actually, if you do your research on these, you will see that it is not at all uncommon for them to die. In fact, they frequently die in a matter of months as a result of starving to death from having consumed all the available microfauan out of the sandbed. It is extremely rare for them to survive for more than two years. For $12 you can go wrong, these need to be left in the ocean where they can survive long term, not imported into the hobby where they cannot and end up dying of starvation.
