To have crabs or not?

[sng]

I have a Bio Cube 29g, Starting to put in some expensive corals! Im just wondering how many people have crabs and how many dont...
Right now i have a Sally Light Foot, and 2 Emeral crabs. Planning to take out the Sally Light Foot soon, since he keep chasing my shrimp goby around the tank.
I hear many horry stories about emeral crabs eatting corals, so should i take them out too?

i have a 12g aquapod w/ a couple hermits which haven't touched anything. hermits and emeralds in my 125 for a little more than a year w/ no problms. if anything i would be more worried about the sally then anything

IMO snails are much safer than crabs in a clean up crew, they eat the same stuff, if not more, and they don't fight.

Just took out my Sally Light Foot... Keeping the 2 Emeral Crabs in the tank...
Hopefully those emeral don't cause any problems in my tank when I start adding corals. Do anyone know if the emeral will try to ambush my shrimp goby? Im also planning to get a flame hawk and a scooter, will the emeral crab be a problem since most of my fish are land/rock fish.
