Is this a Sunstar?

[block134]

Not sure what I have but to me it looks like a tiny Sunstar. It is about the size of a dime and was moving around. I picked up the rock to take it out of the tank and it fell off. Hopefully it is reef safe or I find it again.

Asternia starfish. Some see them as a nuisance.

Some species of them do in fact eat coral. Also they multiply very quick.

I will add that they are no longer Asterina spp. But Aquilonastra spp. There's 28 species if I remember correctly, all but a couple are completely harmless and we rarely see species that eat coral in the hobby.
