I was pulling rock out of my Q.T. and rearranging and I found a tiny crab.... thought nothing of it. I put the rock and crab back. Put my second cleaner shrimp in, as the first one didn't make it. A week later the new shrimp was half dragged under a rock...grr!!!
Then missing.

Had the crap scared out of me the other day when cleaning some live rock in my sink. Was rinsing it under the tap, and out crawls this 2 inch black ugly thing, looked like he was ready for a fight. I nearly dropped the rock.

And this live rock is 10 years old in this tank, so he must be pretty old....

Have never seen a crab before in my tank, probably have a few others then, that never show themselves.

Use to have a big Green Bird Wrasse, that would need anything that resembled a crab, shrimp or snail. But I guess he never found this one.

How long do these crabs live?

I had 3 of those exact guys in my 90. To be honest I kind of liked them, they never bothered any of my snails and seemed to go after all sorts of detritus. They started out about 1cm across, and by the time I broke the tank down they were close to the size of the crab in the pic, one of them even started carrying around clutches of eggs!

I had more problems with hermit crabs eating snails

Crabs are opportunistic feeders and will sooner or later take out something of value. There is no such thing as a nice crab! Oh wait.........a dead crab is a nice crab. KILL IT!!!
