Easiest Starfish to keep

[Rickyrooz1]

What is the easiest starfish to keep? I have one sandsifting sea star but want to get another kind of starfish. How hard is the Blue Linckia (Linckia laevigata) to keep? I am also interested in the Marble Sea Star (Fromia sp.)
and the Orange Sea Star (Echinaster sp.).

All three are listed as bad choices in Calfo & Fenner's Reef Invert. The only sea star they list as good is Archaster typicus, a sand sifter. They recommend a minimum 100 gallon tank for any sea star so you would be overstocked with two. A better choice would be a brittle star.
