Small Grey Star Fish in Tank

[Kumaran]

Hi Guys

I'm really new to marine tanks, I've been running my tank for about six months now. In the last week I've notices these tiny grey star fish appearing on the live rocks. Is this good? Should i leave them? There's alot of them coming up everyday.

A pic would help.
But it sounds like Asternia stars

they do multiply by themselves. Some guys do have issues with them, but it seems to be more the dark blue grey ones. I got loads in my frag tank and no issues with the corals that I got in there
