ID Help Needed

[sunny]

I have two different things growing on my live rock. The first one is white and bubbly. The second one is white and brain like. The third photo is for perspective. Please help me ID thanks.

I don't know what it is, but your rock set up is really cool! My guess would be sponge.

Are they alive, or are those only the skeletons?

They are alive and growing.
