Small snowflakes like things growing on glass?

Hey

I have something growing on the glass in my tank.. they look like small snowflakes.. they have a round white center and they seem to have legs that come off in differnt directions. they are very small they seem to come back about an hour or so after cleaning the glass..
I am thinking feather dusters because on the back glass which I rarely clean I have some definitley little feather dusters
any ideas??

 

They are harmless little organisms, they will keep coming back. I can't remember what they are called but they are no big deal, most fish eat them. I have them also.

 

thanks I had seen them before too but hadn't seen anything try to eat them yet

 

Do they look like microstars? If not I don't know lol

 

yea they kinda do ive seen them before but they don't seem to do anything they are just there... all the time any thoughts on what reef safe fish would eat them??

 

I think most fish eat them, maybe Mike or agansoo will know.
