I'm an idiot. 
I started cleaning my tank and had it half emptied when I noticed one of my fiddler crabs not moving. I made a motion at him to try to get him to move so that I could move the rocks without harming him, but he did not move. I then pushed him and he just fell over and was limp. Panicing I reached in and picked up the lifeless crab and held him in my hands sad at my apparent loss when I noticed something.
My apparent loss had no insides.
My crab molted and I was mourning his "shed skin"
My fiddler is currently alive, well, and very happy wandering the tank, and I will never live this one down lol.
