I have this starfish the size of a dime. It is white with a brownish or redish top. It has 6 arms. It moves fast for a starfish. I will try to post a better pic later tomorrow if i see him.

One of the Astroidea Starfish, they really don't get much bigger.
They call em Asterina

The ones I had in huge quantities were harmless - but I've heard speckled anecdotal evidence of them munching on corals...
keep an eye.
Mine used to hang out a lot in the overflow areas - my guess is they were eating the sponges that were inhabiting the low flow high particale content areas.
