Sorry if I'm am posting in the wrong place. Does anyone know what is growing in my live rock (see pictures)?

Should I be trying to get rid of it or is it harmless? It started growing on my rock about 2 weeks ago and is spreading.

They're harmless.

Harmless unless they start crowding out other stuff. I have them in my tank but they don't spread because one of my fish eats them - probably the dwarf Angels.

Assuming the yellow stuff the previous posters are correct. I've never had the yellow choke anything out.

They are fantastic filter feeders!
