Not the clearest photo but it almost kooks like the legs of micro brittle star. In that case they are a good guy (assuming thats what it is).

Thank you guys so much! Any idea why my old, indestructible star polyp is dying? I have added nothing, change 5 gallons every three weeks, only have 2 clowns, hermit crabs, emerald crab, and a hammer coral--in a 14 cube. 6 hours of light a day.....thoughts?
