I strongly disagree with the purchase or recommendation of a Linckia or a Fromia for a small young tank. These are delicate stars, and long term survival is poor. There is also a big risk in the first month...water conditions must be PRISTINE and what is "perfect" for fish is often fatal for these animals.
They do not eat "algae," or detritus nor are they part of a clean up crew. They will not help keep a sand bed clean. They rely on healthy mature LR in a large tank. For a blue linckia, I honestly would not recommend any less than a 100g with 150lbs of LR minimum.
It takes 12 to 18 months for them to starve...this is a don't count your eggs before they've hatched. There may be no signs of trouble until then.
Brittlestars and serpentstars, for the most part, are excellent additions. But I never recommend a sand sifter, ever, as nearly all will starve in smaller tanks in 12 to 18 months after eating all of the beneficial fauna in a sand bed.
I'm not trying to rain on anyone's parade, but these are difficult animals to keep long term. They have very special needs but most are not provided. Their lives are pretty short in captivity.
I am quoting R. Fenner the various Linckia and Fromia choices seem to feed on algae detritus and microbes in the rocks and in the sand
