I've gone through about 10 red claw crabs that have scuttled out of various tanks in the past 2 years. I've completely given up trying to keep those things; unless your tank is completely sealed with duct tape, it seems they will inevitably manage to crawl out somehow, leaving you with the aggravating task of finding them dried up somewhere in the house.
Ghost shrimp also have an irritating tendency to jump out of a tank, though nowadays my fish generally manage to gulp the majority of them down before they have a chance at doing that.
