Duncan question

[Funwithreefer]

So my Duncan was my first coral about 3-4 months ago. It looks healthy, opens up nicely every day and appears to have 3-4 new heads sprouting right under its canopy. The base of it also looks like it’s growing as it’s spreading out over the frag plug more and more. So as I was looking at it closely I noticed something odd at the base. I wasn’t sure if it was just part of the growth pattern in the way the base grows out or if I have some kind of parasite. Here are some close up pics. Let me know what you think.
Thanks!!

Looks like sponge.

Looks like sponge.

oh didn’t think about that. Would that be bad?

It's a harmless sponge.

Actually I have some white stuff growing on the trunk of my frogspawn, which hasn’t really been fully opening the last few days. I’m wondering if this may be a sponge also. And if anyone knows what those white spots are, I have them all over the back wall and on the live rock. I assumed they were snail eggs of some sort. They are hard and difficult to remove.

Yep...both are sponges. No worries!

The stuff on the duncan is a sponge. The hard white things on the frogspawn are probably spirobid worms. The larger white thing could be a sponge (such as a pineapple sponge) if it's soft.
