Please help ID my starfish

[nanokiper]

Bought this from local fish store. They said this is duoble starfish but when I checked whether it is reefsafe, I could'nt find such name in the internet. Please help ID this little creature. Thanks in advance.

It's Iconaster. They're reported to feed on sessile inverts, but when speaking about sea stars that pretty much means their diet is unknown. That also means they're extremely hard to keep alive and there's no guarantee that they're reef safe.
