How often do ruby crabs molt? When searching for my ruby crab i found what i thought was him but dead, i even poked at it and no movement. I continued pulling rock out of my tank when all of a sudden i felt something crawling up my arm
scared the h3ll out of me but yes it was my crab
. I looked back at the rock and sure enough molt was still there! So my question how often do they molt? should there outer shell be taken out of the tank when this happens or is it no big deal? thanks
