Zero clue what this Zoa hitchhiker is

It started at the base and has grown up the polyp and is now spreading outwards. I posted it last week but the picture was not the best so I am trying again with some better pictures. The frag was dipped before it went into the tank. If anyone knows what it is and what I should do please let me know. Otherwise I am thinking I should just pull the frag out.

Not sure - possibly colonial tunicates? (Examples in the quote below.)

If so, they should be harmless, though it looks like yours would be an invasive one, so you would likely want to make sure you keep it somewhere you can easily trim it back if needed.

Haha, yeah sorry - that's part of why I threw in the TLDR at the bottom there. Here are some photos of colonial tunicates with similar body structure (and some with - from what I can tell - similar coloration) to help decide if it is a colonial tunicate:

And the link below has a bunch more pics (some are different colonial tunicates like above, some are solitary tunicates):

Looks like small colony of barnacles

Looks almost like a blue clove polyp (or something similar) to me… I’d toss it.
