Last night I saw my emerald crab picking at the rock that my colt coral colony is on. I did not seem him actually grab any of the stalks, but he was grabbing in between them all over and it was making me nervous.

I don't know the exact anatomy of this coral, but it appears they have a bunch of polyps on a "sheet" that covers parts of the rock. The crab was definitely eating some of the "sheet" that did not have any polyps on it. Maybe the polyps hadn't grown there yet, had died, or he already ate them, I don't know.

Is my crab guilty of high treason? Or is this behavior probably safe?

QUILTY! had three in my 75 reef to eat bubble algae, saw the biggest one munching my trumpet coral (ripping apart is more the word for it)had i not seen it ,i would had not fingered the emerald's as a culprit. the next day i was watching the big one trying to "prune "the plume off my feather-duster!had to darn near remove the entire contents of the tank to get the lil' bugger.found one of the smaller ones too on a piece of LR i had put in a styro .needless to say i had no choice but to "feed "my clown trigger and porc. puffer in my FO tank. hated to do that ,but at time,it felt like a fitting sentence for the crime (my wife "layed down the law" on them,after seeing it eating the polyps)on the plus side , it gave me an opportunity to re-arrange the tank and frag/divide some green star polyps and xenia's .

I was just about to bring up junkzoo's topic from last week also. All I can say is once is enough. Get rid of him.
