These started showing up on my glass :/

I see these showing up on the aquarium glass and are about the size of a pin head. Any clue?

Dude I just got these also lol. Transferred everything over to a new tank and noticed them. No idea, maybe some kind of feather duster?

Hydroids

Agreed -- hydroid.
Suck it out with a turkey baster.

I found one that looked exactly the same a year ago after adding some QT'ed inverts.
I've never seen another one since then, thankfully.

Everyone is saying hydroids which sucks as the tank is only a month old. I got the rock from gulf coast liverock which comes from the ocean and it has an amazing assortment of life on it but I guess you get the good with the bad. People say they like pods which I have a ton of. Maybe it's time to introduce a fish in my nano.

They usually pop up on new tanks with live rock.

They will die off on their own.

They are a common sight in new tanks, and usually die off. If your tank is only a month old, I'd say to hold off on adding any fish, its still going through the early cycling stages. Give you bacteria biome a chance to get really going before adding anything

As mentioned, hydroids that will probably die off; more specifically, though, you've got Cladonema radiatium hydroids:

Cladonema radiatum.

If you want to try and keep them, you would need to supply a healthy amount of zooplankton (rotifers, copepods, baby brine shrimp, etc.), and see what they eat. You would also need to care for them through their polyp stage, which you can see in the thread below:
