Probably Brittle Starfish. Not bad at all. I actually used to by them off people to put in my tank.
Are you going to the meeting tonight? Forest is an expert on Star fish.

If they are bluish gray asterinas, kill them, kill them as fast as you can! That color has been eating my zoanthids along with the beneficial cleaning they do. Easiest way is to pull them out one at a time.

Both the short, thick arm Asterina Star and the long, thin arm Brittle Star reproduce in our tanks.
Here is an Asterina Star on the glass doing it's main job. 
Here is a Mini Brittle Star doing the spawning thing. 
BTW, Sea Stars are not fish.

Typically Asterina Star like the ones in Mark's pic are good to have in your tank. From the reading I have done the bluish colored ones are the most likely of them to become problems by eating corals. I used to have MANY Asterina's in my tank and never had a problem, but if found blue ones instead of white ones I personally would start pulling them out.

There's really no way to tell if those Asterinas are good or bad until it's really obvious which they are. I've had bad white ones, good blue ones, and horrid speckled ones...in addition to the good white ones, bad blue ones, and every other color and temperament.
Please don't get a harlequin shrimp to eat them, unless you're willing to supplement its diet with large starfish. Manual removal is best if you don't want the starfish.

Oh good luck with that uphill battle. That's worse than trying to get kids to stop calling every clownfish, "Nemo".
Kid: Nemo, Nemo Mommy! Mommy: No hunny, that's an ocellaris. Can you say ocellaris? Kid: NEMO!!!

Yeah, last night Forest Gahn, the Echinoderm specialist, talked about "Starfish". Not once do I remember hearing him use the term "Sea Stars" or "Stars". Oh well. 
Forest was an informative and entertaining speaker. His recounting of the voyages in the DIY submarine were hilarious.
