Tiny anemone like creatures on glass

[logibear]

Can anyone tell me what these are? I have found 4 of them on my glass today. They are very tiny so hard to get a great picture of but they are all white and look like anemones of some sort.

Could be an anemone, but more likely to be hydroids.

thanks! I think that’s a best case scenario situation
