Oak - was the hystrix showing signs of failing (losing any of the thin tissue skin) before the cleaner shrimp "cleaned" it? I've only had my fish or inverts pick at corals when the corals were on their way out. It seems like SPS lately are being chewed up by unexpected types of fish and inverts - strange.
Glenn/Tammy - thanks. That second pic is my newest coral - a green birdsnest. It's already shown some good growth in a short time. One of my Turbo snails ate that Bryopsis algae that was growing on the left side. Now some Majano anemones have appeared where the algae was. I'll have to deal with those with some Aiptasia-X. It's a constant battle in my tank.
