What is this on my frag?

Does anyone have any idea of what this is on my coral plug?

Take a picture with more white less blue if possible. It could be a sponge or baby mushroom.

It seems larger now compared to when I first bought the frag...

Ok I think it’s a tube worm actually. You can see the growth of the shell.

Keep it on the frag/in the aquarium, or no?

Might be a vermatid snail, no good.

Looks like a vermatid snail, cut it off the plug with bone cutters. They can irritate corals.

I think you have two types, like @Rjukan mentions the left tube looks like a vermatid. Not sure what the right one is, probably tube worm like @emilio365 said.
