What can this be ?

Those three tiny little things are growing next to a mushroom on my rock .... they are no more than 1-2 mm each (Its wierd that I actually saw them) ... What are they ??? Should they be removed? Could they be Xenia ?

Looks like Xenia to me.

Looks like a soft coral as you already guessed, it will have to get a little larger to be specific. Does it pulse at all? While the unknown is next to the corallimorph it does not looks like a mushroom type coral.

Ι do not think it pulses .... but as you said it is too small ... I cant say ... If we take the worst case scenario of it being Xenia, is it safe to wait a little bit before removing it or can it spread in my aquarium? Problem is it is too small that I cannot remove it yet...If I grab it with something it will dissolve rather than be removed

I had some baby Xenia sprout up and killed it by covering it with Aiptasia X. I think that's a much better solution than trying to pull it off and risk spreading it.

Dont have aptaisia X. But could it be a solution if I covered it with epoxy ?

That would probably work fine. Do you have any Kalkwasser? You could make a paste to cover it with.

Definitely looks like Xenia to me too

Can I siphon it when doing water change? Like rubbing it with something in front of the tube so everything is sucked up immediately ?

I'm seeing Kenya tree...

Either way, very invasive.

Yes, provided you get it all.

To me it looks more like a leather coral. Xenia would have more elongated polyps and Kenya tree would be less sturdy. I would wait and let it grow. In my eyes none of them are as invasive that you would have to kill them at this stage. The mushrooms can be invasive too and spread all over the tank.
