parasite, sponge, invert???

What are these things in my tank?

these are on the bottom of my bubble coral, they are also in my sump, and on some other rock work in my tank. I have no clue what they are or if they are bad for the tank, any help is appreciated.

They are pineapple sponges, Not a problem they are good filter feeders ..... Shows that the tank is establishing well......

I have those too in my tank, probably a few thousand. They hang out mostly in low light levels underneath on my LR. They do look like a pineapple now that I think about it. Glad to learn something new everyday.

They look like Q-tip sponges to me?

Reef-on everybody
