White specs on glass?

Diatoms? What do you guys think? They are all over the glass. I just cleaned it not too long ago and these popped up

They are baby brittle stars! Very good little cleaners. They eat detrius

mr. scotty sent me a pm. Telling me that they were hydroid jellyfish. A quick googlr image search prices correct. They are relatively harmless and the population should decimate eventually.they are suited for lower flow environments, hence the reason they are clinging on to the glass.

They are hydroids, your friend is correct.
