Emerald crab dude. I never knew they would do this until some of my zoos started turning up missing just like yours. They one night i seen him sitting on a big patch of zoos plucking them off one at a time eating the whole thjng one after the other. He went through a hundred or so polyps before i finally discovered this and removed him and put him in another tank.

They are opportunistic.

Yep i was stunned too. I watched him for over and hour eat one after the other. He went through 3 entire colonies of orange bam bams, rastas, and eagle eyes. One expensive meal for an 8 dollar crab. He may have also eaten some xenia however i can not confirm that.

Emeralds are either hit or miss. Some have no issues, while others have issues with them picking at corals. I tend to believe that, since they are scavangers, when they pick on some corals that they aren't doing well and that the crab is just doing his job. This of course isn't always the case. In a tank where there is little algae present, what is a crab to eat? They don't want to starve to death, so will find the next best thing.

Yes at the time this occurred my tank had zero algae and in my experience under those conditions crabs become very opportunistic. The polyps he ate were healthy, however if he had nothing else to eat then he had no other choice. But yes it is hit and miss. Ive had about 8 emeralds and half of them were peacefull reefsafe, the other half not so much.
