Undecided about Emerald crab

I'm undecided if I should get an Emerald crab or not.
I really like this crab and heard they are extremely beneficial and usually peaceful but I had a nightmare in the past with a Sally Lightfoot that started to go after the fish and now I can't decide.
Anybody had a nightmare with and Emerald?

I love my emerald crabs (5) they will "try" to grab a fish when they swim by at times but i do not think they really could do much harm? I had three then on Monday added two more the two big ones fought for an hour or so to determin who was the badest.... now all seems peaceful.

I have two in my 65 but plan to add more. They are nice to watch and always seem to be shoving things in their mouth. I'll probably add two more when I increase the amount of rock.

To the op, emeralds are nowhere near like a sally.Emeralds are a good addition to a tank especially if you have lots of junk on your rock.

I had an emerald in my reef and I caught it one day eating my frogspawn.
I haven't owned one since. I guess they all can behave differently though.

When I put 2 of mine in, one feasted on my zoo's.... tried to get them out asap, only able to get 1, the other must have burrowed, haven't seen him in days...moved the other that I could catch to a FOWLR tank. I won't get more to say the least.

I have an emerald crab in a 26 gal with a good deal of inverts and fish considering the size of the tank and it hasn't harmed anything. They're probably one of the coolest things in my tank.

speaking of emerald crabs..... MY CRAB IS MISSING A CLAW!
guess the two got into a fight and one is missing a claw. the girlfriend says find the claw and super glue it back on lol.

I had a set of them in my 14G.. one got WAY to agressive so I took him back and just left the one. then the one that was left started picking on corals so he got the boot at well. now I seem to have a very mellow one in the tank again to help control that hair algae. I really think they do lots of good, sometimes you just get one that is going to be a pain and knock things over and pick on corals. my current one... doesnt really hurt anything. I say go for it

I haven't had the greatest luck with them.
Not sure if its the source, there wasn't enough food, or what, but neither I've had has lasted more than a couple months.
