Hi everyone, I haven't been around for a while, but I'm still crabbing. My most active crab, Rowdy, has molted several times in the past year--I think. Is this possible? I know the little ones molt often, but Rowdy is a large medium and has doubled in size since I got him. I think he's molted at least 4 or 5 times. Any thoughts on what is going on down there?
