Also known as The Astropecten articulatus. I had this starfish for about 2 and half weeks now. He seems pretty active moving around,but I noticed that he sifts he way into the sand,and would stay there for a day...Then moves to another spot and buries himself again. I tried to feed him mysis shrimp and clams on a half shell but he just moves over it and buries myself into the sand...Does anyone have any information on this breed of starfish? What to feed it, and tips on how to feed it?? I've added a photo so if anyone has any information it would be helpful...Thanks!
