Larvae?

I noticed this, this morning posting a few pics kinda hard to distinguish but any help would be appreciated not sure if I need to remove. One of the pics for reference had my foxface poking in the hole.

This is a tube for vermetid snail. Place a dab of gel superglue over the opening to starve it

Are you referring to the slimy material in the hole? Looks like a sponge, which are generally harmless filter-feeders. On the off chance it smothers coral, you can inject it with boiling water, hydrogen peroxide, or air to kill it.
One of my sponges (note the transparent oscula or openings):

Yes the slime seems to be around the inside of the hole, I'll see if it grows into a sponge. Just didn't want something to burst into a million unwanteds.
