Emerald Crabs

Are emerald crabs reef safe?

I ask because I have a large colony of candy canes and one of my emerald crabs was crawling deep inside of it. Wasn't sure what it was up to.

They are really good at removing unwanted algae deep inside corals. I never had a problem except the normal damage from there work inside new corals like glove pylops or zoas with unwanted algae in between.

I had to get rid of one because it would also climb in my birdsnest and pick at and eat the polyps.

I would suggest a search on this site for "emerald crab" and count the number who've never had a problem (I have seen three people say that) and then count those who growled and struggled to catch their little coral killer (happened to me and I've lost count how many others). Essentially, it's like Russian roulette, except in this game, only one chamber is empty.
You may beat the odds and never have a problem. But I wouldn't bet on it. I've removed two for eating coral, and there was no shortage of other food available.

Crabs in general are opportunistic feeders, if given the opportunity it'll occur. I have 3 emeralds in my reef without problem, but I truely feel that due to my constant algae growth has kept them so fat that there hasn't been a chance to think about munching on anything else.

I'm an emerald fan, I thought I had a problem when I seem him in a half devoured torch coral,
It turns out the coral had a disease and good old crabby was cleaning up the messy dead bits.
Ps, I've got two

I honestly think it depends on which emerald crab you have. I've heard stories about them not bothering anything for a long time, then all of a sudden they eat corals.
