"These peaceful omnivores are a great addition to reef aquariums. They will consume detritus and left over food. Like other starfish, this member of the Astropectinidae family also consumes small invertebrates, including shrimp, urchins, mollusks, bivalves, or other small sea stars. As such, they should be actively fed with a varied diet that mimics their natural food sources, especially in well-established marine aquariums. Otherwise, these voracious feeders can quickly clean your aquarium of detritus and then bury themselves into your substrate, starve, and eventually begin to decay."
And if your still interested in a starfish here's a bunch of them also which you can read about to pick which would be best suited to your aquarium.
