sand sifting starfish are the reason your sand bed looks bad. (in part)
they are predators they eat the benificial microfauna that inhabits your sand be. one star alone can decimate a suprisingly large area. havbing several just wrecks the natural balance of your sand bed and will lead the the eventual starvation of the stars.
you want detritivores not carnivores. bristle worms, serpent stars, proper flow, nassarius vibex snails, and other things that tunr the sand without preying on the animals.
there are a couple sand sifting cucumbers that will help. you want either the black cucumber (Holothuria atra) or tigertail (Holothuria hilla), neither of these are highly toxic, no more ttoxic than a fish of equal mass if it were to die. my first choice would be the black cucumber Holotrhuria Atra. I have several of both types and the black is the more dilligent cleaner of the sand. I would not start with more than 2, if there is ample food and range sometimes they will reproduce asexually. primarily nocturnal dont be suprised if you dont see them out and about a lot during the day, although my black cukes dont seem to know they are nocturnal and crawl all over the place day or night(including the rock work looking for detritus in the crevices that my seastars dont snag)
OK so i just purchased 1 sand sifting cucumber 2 serpent stars and 25 nassearius snails they should arrive tomorrow. What should i do with the sand sifting stars. Leave them or remove them?
