Hydroid jellyfish? I think?

[TheClemsonKid20]

So I found a whole bunch of these guys on the front glass when I got home from work this afternoon. I’m getting a lot of mixed answers on what; if anything, to do about them. I’m almost certain they are hydroid jellyfish. What I’m not sure about, is if I should do anything about them.
I have a new tank (about four months old) with 25lbs of cured live rock, two Darwin clownfish, a skunk cleaner, purple dottyback and a cleanup crew consisting of turbo and hermits. The fish and shrimp don’t seem to notice them. I’m hoping the cleanup crew will eat them, but I’ve heard they sting? Any info would be helpful, thanks in advance!

This is a hydroid. If on the glass, simply scrape off with the edge of a credit card into a net and discard. If on rocks, simply starve them. They favor brine shrimp and what you want to do is direct water flow towards them - Not at them to prevent food from reaching them. They will weaken and die off.
Last method is using Gel superglue from the dollar store, place a dab on each head of droids and they will starve off and die
