Monti has white spots

[Dan P]

I had a Diadema long spine urchin that used to take bites out of my Montipora. I got rid of it and the bite marks never reappeared.

It looks about identical but no urchins in my tank. Pretty short list really, hermits, snails, pompom crabs, pistol shrimp, emerald crab (not in the tank when the sunset monti was injured), banded brittle star, clownfish.
