How to tell if starfish is dead

[salty tank]

How do you tell? Mine hasnt moved in like a day and even before that he didnt move much. I bought him saturday. Will his color fade?

hey you'll need to post your water stats. Have you tried seeing if he moves when you add food to the tank. At first mine didn't move much but as soon as I add food all her little feelers went out

What kind of starfish?? Some move a lot some don't. If he is there all in one piece, he is still alive, believe me,..you will know if he is dead.
