help id this starfish!!

[marvinsae]

just found it today. it is very small, about pea size maybe a little bit smaler

[outacontrol]

I think it is a astrea

[xtreme]

I think you mean Asterina.

[marvinsae]

if it's an astrea i could just pick it out but i've heard that some people have asterina outbreaks. maybe i should get a couple harlequin shrimps? do they go well with other shrimps or a bristlestar cause i know they mainly eat starfish but the bristle is pretty big...
