Found these on the glass amongst the copepods. What are they?

What are these? They are on the glass this morning with the copepods. Looks like there’s feeders coming off of it. It’s really small, but bigger than the copepods. This is the best photo I can get.

I looked up hydroids and it does look like that. Any experience with them? Good, bad?

They are an annoyance, but not uncommon in newerish tanks. You may see a boom in their numbers, but they will eventually die off. Take it out if it makes you feel better.

Had so many on the glass of my newest tank that you could see them from across the room. After a few months they went away.
