Thought it might be aiptasia? Anyone know?

I got this stuff growing in my tank, my first thought was aiptasia, but with it being white makes me unsure and with it not really having a head. Anyone know what this is? I'm a new reefer I have no clue.

Looks like sponges. Cannot remember the exact name though.

My closest guess would be
Clathrina coriacea (White Lace Sponge). With so many species, I am probably very wrong. It's safe, depending on who you ask. up to you if you want to keep it or fight it.

I don’t think it’s a pineapple sponge, but they’re probably sponges.
