What are these?

So I'm waiting for the tank to cycle and looking at all the micros that are in the glass. I came across these and took a picture with a magnifying glass. They're about the size of a pencil tip

Any ideas?

Hydroid jellyfish medusa. Normal during the beginning stages of you tank. They will die off.

Die off? Too bad. Right?
Besides copepods and isopods I also see what appear to be several Ramshorn snails but with a feather duster body coming out of the shell. These appear to be stuck to the glass also. ???????

Those would be Spirorbid dusters. If they bug you, just scrape them off with a single edge razor blade or plastic scraper (if your tank is acrylic).
