Small white circles on Live rock and snail shells

[thommyboy12183]

I have recently been seeing small white circles form on live rock and snail shells. There are not many but i am trying to identify them before they expand(If this is a parasite) any help would be greatly appreciated please see attached pictures from rock.

Tube worms. Harmless. I have millions of them.

+1 on tube worms. They are filter feeders, so they are good.

 

[Sugar Magnolia]

Spirorbid worms. Harmless little filter feeders.

Great, i was concerned it was a fungus of some kind

Is it worth controlling these worms/is there a way? They are all over the glass, rocks, shells of hermits and snails.

Not a huge deal i guess it just doesnt look "good". IMO always think the tank is dirty

You cannot really control/fight them.. You can scrape them off the glass but other than that.. just leave it and get used to it..
They and other critters will be all over shortly..
It looks "natural"
