Looking for an Id

[Pierre96]

So I am starting to notice this on my live rock. They were pretty small and now getting a little larger. From what I have been researching I think I know what they maybe. I seeing if someone else knows. Pretty sure I am concerned about these little guys. Hopefully it's not digitate hydroids. If they are, beside nuking the live rock wondering if anyone has had success in keep them in check or getting rid of them. I have found various things online. Looking for people that have battled this. I've heard sea hair, file fish, bubble bee snails, a type of nudibranch that u can't get, etc. Hopefully it's something beneficial. The live rock I have had for many years. I do overfeed my tank. Thanks!!

Hydroids

Hydroids

Great :( Probably not going to go away?

Yup, Hydroids. You can use underwater expoxy or remove the piece.

If anyone has any ideas on how to battle them let me know. Reading some people have used Fenbendazole. I really do want to do medications

They are on 3 or 4 separate rocks. Hoping there possibly could be a predator for them. Fun

So I bought 4 peppermint shrimp and bumble snails. Also will try Joe's Juice. Also will remove a rock and try to scrub it. Hopefully that will work. Step one I guess. It's weird to me but looks more like aiptasia. Not really a stem, more like a stalk at the base. Glad I don't have lots of corals but not a fan of aqua scaping.

Has anyone tried aptasia x on these?

Photos are a little blurry but assuming these are hydroids I dont think the snails or shrimp will do anything, they arent known to eat them. You might already know that though, a little confused by the wording of your post. Aptasia dont really grow like this, in close clusters together, the heads look pretty small for aptasia as well.

Yeah, I've been looking at pictures and what I have seems like the stalk looks more like Aptasia, not really a stem. I didn't really get a good pic with my phone. But yeah probably not aptasia. I have never seen it grow like that. I am just going to try a few things slowly and see if anything helps before I start removing rock.
