I found about 10 of these on my zoa rock when I did a dip. My zoa started just dropping polyps so I went wanted to dip them. They are large up to 1/2 inch long ways. I cannot believe I did not see these I am not even sure they are the problem. A little crab even came off I could not find on the hitchhiker list. Thank you
