I have 5 in my 55 and they are fine together. SWF.com list them as peaceful.

They will pretty much ignore each other, other than getting all "yo yo yo, what you doin here, back off!" when they bump into each other from time to time, if they even notice each other.
However, they are not 100% "peaceful" to ALL life, guaranteed. Like any crab, they will eat just about anything if they come across it, are hungry, and figure it won't be too much trouble to nibble on, especially as they get larger. This includes nibbling on corals and even killing fish. This isn't COMMON with them, and they along with sally lightfoots are probably the tamest crabs there are available to the hobby. But it's worth at least acknowledging as a risk, even if its a small one.
They other issue linked to that is that like many crabs, they can be a pain to get out of the tank if you need to remove them (like if you want to banish a rowdy crab to the fuge). They hide in LR at the first sign of you interfering in the tank, and often you won't be able to get them out unless you remove the rock they are on and shake them off it in another tub, or trap them. Not quite as bad as some fish, but nowhere near as easy to remove as hermits.
