Found today on live rock

Can anyone tell me what this is? I am new to salt water aquariums. I found this star fish looking thing on some live rock today. It is very small maybe a centimeter across.

Found one more smaller one, looks exactly the same. They do move, just very slowly.

Yep but but don't they munch on Zoas ? I would keep it in the sump not the display tank.

I think it's just the luck..or unluck..of the draw on whether or not they munch on zoas, i've read that they do and they don't. I had one, but the last few days he's been missing

They are usually all over live rock and sand, some people use harlequin shrimp to keep them under control in larger established tanks
