I have these white things growing out of the small holes in my live rock. There are very small tubes growing out of the smallest holes my live rock and connecting at a big white bubble. It looks kind of fuzzy. I tried to take some pictures.

Those are most likely just sponges. They usually grow in areas that don't get much light, under ledges or shadowed places, as they are non-photosynthetic. Just harmless filter-feeders.

Hard to tell but kinda looks kike pineapple sponges. Beneficial filter feeders.
