Once the food supply is gone they will find a new food supply... If you have zoas, pull the emeralds.. I agree that they are great cleaners and are diligent workers, but they have a wide range of tastes...

I had 8 of them in a 120 and eventually I busted them all eating zoas. Also caught them scraping their claws on my sps.

My emerald fell into my rbta but he was a good cuc member for me and always hid during the day

Most likely as emerald crabs are more active at night. I get the small ones also as they are more likely to eat BA and less likely to eat other CUC members. I have bought dozens of them over the years and only had a single issue with one eating a bunch of hermits and snails.

I've seen them eat zoas and some acans.

Well,So far so good,I have very few soft coral.If they just leave my sps and fish alone.Im ok with that.

I put two Emeralds in my tank to eat some bubble algae. They ate a bit of it. But most of the time I found them eating my zoas, acans and anything else they could get their claws on. I had to remove them. I gave them to my girlfriend to put in her tank and eat her corals.
