milepora crab id good or bad

[edmondspl]

Hey guys. I have this little fellow on my milepora. I've lost PE in the last week and inspected it and found this guy. Just wondering if he is the culprit.
He is the fuzzy kind if you can't see it good enough.
Thanks

I think the general rule of thumb is that fuzzy = bad.

Cymo melanodactylus. Well known for eating sps tissue. Best to remove.
