please advise

Looks like a dirty asterina starfish. I would say friend. Some say certain ones eat zoas but I have never had an issue with them

 

[ChrisfromBrick]

ok- i have smaller ones here and there i just want to make sure this wont eat corals

Aquilonastra sp. or Asterina sp., if you keep Zoas: Foe, if you don't: Friend
Not all eat zoas and if they have enough other things to eat they might also leave them alone, but I had the meat some VERY expensive polyps

thank you yes i have zoas. Some are declining and im wondering if these are responsible.
