Something growing on my rock and back chamber of my tank. Looks like eggs/worm

Can anyone ID these? It started under one of my coral plug, then just saw a whole lot on my back chamber.

Thanks !

Welcome! They are Pineapple Sponges. Nothing to worry about, they will come and go.

He’s correct there just pineapple sponges and there usually a good sign that you have some fairly decent water quality, also I’m just now realizing the similarity’s between the pineapple sponge and spongebobs house
