I love my little emerald crab, they do an awesome job of clean up- there's a chance they could have been cleaning the inside of your rocks if you don't see them for days. Cerith and nassarius snails are pretty handy!

Do emerald crabs kill coral or fish? I want to add some to my cuc but I don't want them harming my livestock.

As far as I can tell the jury is still out on that one.... Mine won't even stand up to blue foot hermits that are only a half inch and he's an inch and a half (without legs). All he ever wants to eat is hair algae and cyano off my rocks and scavenges for decay in my sand bed. Imho I think of you have a messy eating stock that they probably won't even look at your live stock, just their waste, but all I have with mine is live rock, coralline algae and the usual hitchhiking critters and 3 blue foot hermits. Reading reviews on them it doesn't seem as though people are having problems with them....

Never heard of them killing fish but they can damage corals as they will try to steal food from the coral even by forcing it open to get what it has already eaten
