Unknown glass dwellers-PIC

Can anyone say what these are? Sorry for the terrible pic, they are only about 1/64 inch. Are they starfish of some kind? Or do I need to move to the ALGAE forum. They are white and after I whipe them off they come back the next day. I don't see any type of algae (micro) anywhere. These are white just as in the pic. Thanks.

 

Hydroids. There are a few recent threads here where people have had the same critters pop up

 

Thanks, that appears to be what they are. I think I will leave them alone. I have noticed them since the beginning of the LR introduction and they seem to stay about the same size and I don't see any corals in distress. I will assume they are OK, at least for now. I don't seem to be getting any algae on the glass, sand or rock so I wonder if they consume it.

 

HYDROIDS! Dah dah dah daaaaaaaaaah! (suppose to be surprising sound). I think those dudes are harmless, but some are pretty nasty. Dont worry, they will get eaten up and if they dont, they wont survive long.

 

Apollo this is the thread Am was talking about. You are right rick, those on the glass are harmless. It is the polyp ones that can get nasty.
