I have on several pieces of rock little white things. They look like starfish because they have 5 legs that stretch out and they moved all around the rocks. I have seen 3 of them. There one the size of a quarter and the others are smaller. What could it be?

Could be small brittle stars. Can you post a picture?

 

[scrmom]

That is exactly what they are. I googled brittle stars and that's what I have. Will they do any harm?

I have about 10 of them. Some smaller than a dime and some as big as a quater. They are completly safe and help clean up you rank.

That sounds like quite a few of them. I think some of them may end up starving. Maybe you could sell some of them to your LFS? They are great sand sifters.

I have something like this too- they are all white and hide in cracks and under stuff... I see there legs sticking out of cracks everywhere, my reef tank (30 gal) is THRIVING and all the corals I put in spread like wild fire... nice tank but I have hundreds of these things!!! Maybe over a thousand, if I stir the sand bed they go floating through the current (they roll into a ball when this happens) all over the place, anyways- my tank is thriving with no probles ever with pollution or anything so I just leave these guys do their thing... Mine seem to max out at about the size of a quarter spread out, most are size of a dime spread out and some smaller
