I think I've finally figured it out... I was looking through Julian Sprungs book and he talks about normal emerald crabs and ones that are much larger....
Well I added two of the "larger" ones with MAMOTH claws and noticed my coraline was starting to get eatin..... then I got home tonight and noticed the emerald duking it out with a hermit crab.....
My guess is that the smaller ones are safe and that the mamoth claw ones are more aggressive and capable of pinching of coraline....
buyer beware.....
I've managed to put on of the larger ones in the fuge....looking for the other......
