White fuzz growing under chalice and rock

[COCOBBALL]

Hello new to reefing and my tank is 3.5 months old. I believe some of my first coral may have a problem.

I notice the white mold like fuzz between my rocks then some possibly under my chalice frag.

Anyone know what it is? Is it a problem?

Thanks

I noticed this in another place. More pineapple i hope?

This is more of a tentacle than a mold look.

Welcome to R2R (too late ... ) . I think the second one is a ball anemone or some other critter. I suspect its one big critter, unlike the pineapple sponges. Check it at night, some of them are nocturnal, they extend their tentacle/polyps whatever at night, so its easy to spot. If the tentacles have something bright on their top, its most likely an anemone
