Invasive? Or not?

[ImGood]

Not sure what they are however I should find out . On a small rock amongst the zoas, like mini Xenia except they stay very short( shorter than the zoas) & don’t pulse.tia. Cheers

Clove polyp?

Based on polyp shape alone I'd say Pipe organ coral (Tubipora musica). Do the polyps come out of an encrusting red base or does it look like they are fuse to the rock?

Either way, it's not invasive.

Invasive clove polyps, I would not introduce it to my tank but that is a personal decision.

looks like it’s attached to the rock
