What is this?

I just noticed this looks like little white hairs coming out a pinkish body of some sort.

And this it kinda looks like a slug/worm of some sort I can't get a good pic cause not much to focus on but this is on the glass.

Top one I'm not positive but the one on the glass for sure is Zoa eating nudibranches. Look like they have green star polyps on their back. Get rid of them any way you can. And pull out all your zoas dip them and inspect for small round gold specs. If I remember right salifert flatworm exit I believe it's called kills the adults quite well. Not much if anything every kills the eggs of any creature in this hobby lol.

Top ones look like pineapple sponges. They aren't really harmful - just unsightly. My sump is full of them. If they grow on any corals, pluck them off. They don't seem to do any damage whatsoever and they definitely help soak up nutrients.

Yes it has little green specs on its back side and thanks I'll get right on top of it to get rid of it. Could that be the reason that my zoas haven't opened up? They where opening up all the time and now they just stay closed.

Top looks like it could be Polychaete - Flabelligeridae, please compare image here:

Second could be any kind of Nudibranch, from Zoanthid eater to Leather eater, Montipora eating...It should probably be removed from the tank and if you notice your Zoanthids are closed be on the look out for other Nudibranchs and their eggs.
