I purchased a live rock earlier today and noticed something on it, it looks kind of like some type of coral but not sure what kind. Can someone help?? It is yellow And seems to have some maroon on it too

Looks like it might be a pice of dead or dying montipora. Does the pink part have any polyps coming out of it?

No but it looks like the yellow ones might have a stub of something
