Please identify algae!

I have attached a picture of this unknown algae or diatom growing on a zoa colony. You can see it directly in the center of the zoas where there is a bare spot. Any help would be appreciated!

For some reason the picture doesn’t show up as clear as on my phone.. It has a stalk or stem and then round top almost like a q-tip

Yeah, if possible turn on your white lights only and try and get a better picture.
