Thinking these are colonial Hydroids

[sonoransurvivalist]

I dipped this plug in Brightwell's CoralMD before I added to my tank because it didn't look great... now these things are sprouting up all over it and looking like they're trying to jump to the little rock this is isolated on. Pretty sure these are some type of colonial hydroid but would love a second or third opinion to confirm. Wondering at this point what I can do to rid these of the frag and prevent them from spreading further, they're all up in on these cloves which I'm sure is irritating it.

That plug needs to go.
I use a razorblade to remove softies and hard coral frags from dirty plugs. All work is done outside of the tank. ONce the frag is seperated from the potential contamination (of any kind), glue the frag to a new plug or clean rock.

Is this in a QT tank? GL

Unfortunately this is not a QT tank, the good news is it's isolated far from anything else on a small rock so I can just pull the whole thing and either toss the rock or cure it. I'm not so sure there's any way to save the coral on it... these things are all up in it.

Just posting an update here - talked to my LFS where I bought the frag, and was told that most corals (in this case clove polyps) do not need oxygen while hydroids do, so pulling the frag and leaving in a cup for 24 hours will kill the hydroids causing them to just fall off the frag.

Definitely hydroids but don't think they are colonial. I had a bunch that really multiplied for around a year and after introducing 8 wild peppermint shrimp, they completely disappeared along with the aiptasia.

Thanks, I'm monitoring the area where the plug was, currently don't see any so I'm hoping I caught it fast enough.
