I got a sea star that came over on one of my corals. I would like to keep it alive, but I am not sure whether it is a sand sifter or carnivore. It initially showed up with 5 legs and then was cruising around the tank and filtration areas. It disappeared for about 5 days then showed up missing two legs. Not sure if it got injured under the rocks, or if it got injured in the protein skimmer (it was cruising on the outside of it for a few days, I assumed eating the algae on the outside). I hope it isn't losing legs due to starvation. Can anyone help ID so I know what to feed it?
