Need help with 2 new...somethings

[DBLA]

Number 2 picture is of what looks like translucent small tubes...they are expanding for about 4 weeks, I thought were sponges, but then choked out some a paly frag. I do have pineapple sponges in the tank, but these look different

Number one and 3 is a white spongy growth growing under a frag of coral there is another tube/fan off the side it is soft but firm.

One and three look like sponges. White sponges tend to grow in shady spots. IIRC they can overgrow some corals so keep an eye on them.

Number 2 I have no idea. Hopefully someone else will chime in.

Thank you!

could be bryzoans (the white stuff that looks like a sponge)
