What is this?

Hi all, just noticed these little white hair like things with tentacles in my tank. Not sure what they are. Good, bad? Please any ideas?

I’m following I want to know what those are as well…. @ISpeakForTheSeas Do you know?

Maybe hydroids? Do they stay stationary?

Not really sure, I just noticed them today. Haven't seen any movement. They are very small.

Those are definitely hydroids - I haven't figured out exactly which kind yet:

Yeah, I haven't narrowed down the exact variety yet, but they're hydroids, most likely from the suborder Capitata - they might be an Asyncoryne species, but I need to do some more reading up on the families in the suborder to say for sure.
