He moved into a new shell, and apparently it has a growth on it. LOL ;D

That's a Yuma, keep an eye on them. They can spread fairly quick, move and pack a good sting.

An urchin picked those up in my tank, burned a lot of coral before I figured out what was going on.  I'd look at scraping those off that shell.  Looks neat, but those things are coral killers.
