Need help with id - Little white polyps?

[omahagramma]

Hello. So after finding a bunch of tiny white worms, now I am seeing a bunch of small white polyp like thingies growing in the parts of the tank that don’t get direct light. Photo attached here. I also haven’t been able to identify the white worms but I am thinking detritus worms (not sure since they have been around on the glass for a few weeks now - Photos attached) I’d really appreciate it if someone can help identify both critters.
thanks

I have a idea but as im new dont take what i say as gospel but will bump this for you so someone with more experience can give you more educated answer.
But look up calothrix for them sort of translusance things you zoomed in on under that rock.i had something similar in my tank and looked like this to me and couple experienced guys agreed with me,its kibd of cyano bacteria ( but look it up to see if shapes and everything is similar) as for the worms i also have an idea but forget the name but if what im thinking healthy tanks get them,but as i say i just bumping this so someone else can reply to ya ^_^

Edit: maybe good idea to say how long tank been set up,if its cycled or not.dry rock or live rock used and some information like this helps others ive seen people ask
