How established is your tank, I think they should be at least 6 months before adding items like sand siffting seastars, otherwise there is not enough for them to survive on and they slowly starve unless you can spot feed
dont add a sand sifter starfish, the do horibbly in captivity, to clean the sand bed id get a tiger tailed cucumber, some nassurois (speling?) snails, and some tiny hermits
