will arrow crab bother sea cucumber

[big deddy]

I just added a arrow crab to get rid of some bristle worms. I think he is OK with everything in my tank, but I forgot about the sea cucumber. When I first put the crab in he kinda poked at the cucumber with his leg. I pushed him a little to get him to go back in the rock. My question is will he, can he hurt or kill the cucumber? The cucumber is my wife's absolute favorite thing in tank. If he hurt or killed him she would hurt or kill me! Someone with some knowledge help me out on this one.

Old thread but I would like to know if anyone has experience keeping cucumbers and arrow crabs together.
