Starfish - Reef Safe?

[THX1138CY]

Spotted this guy on my sump wall. Is he reef safe? Is he safe in my sump?

Looks like an asterina star to me... i could be wrong. Pretty harmless but you can have an exploding population pretty easily

Thanks I'll put him back in my sump, if I have issues, I'll get a Bumblebee shrimp.
