Will Arrow Crab grow legs back?

[Shekki]

I've had an arrow crab in my tank for a few months with no problems. About 3 weeks ago I noticed he was missing 1/2 a leg. Figured he got into it with my CBS and lost. About a week later he was missing one of his claws. Didn't seem to bother him. Since my CBS grew an entire claw back, I figured the crab would be OK. A few days ago, I noticed that he's in horrible shape. Missing both claws, and most of his other legs. Right now he's got one full leg and 3 half legs. I pulled him out of the tank with the CBS and put him in my peaceful tank. He does manage to get around and is still eating.

As they molt they continously grow what ever appedage they lost or damaged... not at once but during several moltings

That's what I thought. If he is ever a whole crab again it will be amazing!
