Hydroid Identification

[Niceroc]

Hey all! Relatively new to the hobby with less than a year of experience. Noticed my lepto wasn’t looking too hot and shortly after, I noticed these guys hanging out on the underside of the frag. My searches through the forums lead me to believe they’re hydroids, but I was hoping someone with a bit more experience could help me out with identification.

Thanks!!

Yeah, looks like hydroids of some kind to me.

They are going to spread. I'd get rid of the frag. That's just me.

^^^^ This! You DO NOT want colonial hydroids infesting your tank.
