Does anyone know anything about the electric blue legged hermit crab? I had bought one back in december and I asked the guy at the store if we needed a larger shell for it to change into and his answer was no and that they dont grow much larger. Well....this crab changed into a shell that was much much bigger than he was and could barely move. He now shells hops almost every other day. And now he is a lot bigger than when we first bought him. How big do they actually get? I also believe he killed my horse shoe crab!
