    My crab has successfully completed his molt. It only took him a little over two weeks and he has eaten almost all of his exoskeleton! He hasn’t completely hardened up yet, and he didn’t seem interested in his food and mostly just wanted water. He has now began digging again. Is he still okay and is this possibly due to him not being fully hardened?


    I read online some place that they occasionally do this to come back out and get some water, usually they bulk up and store enough so they don’t have to eat during the molting period. If I come across the link again I will share it, but I’m betting your guy is just going back down to finish up what he started.


    “Look closely behind one side near one pair of walking legs, if there is a small black blob then that’s the fat storing sac. It feeds on this fat when it’s molting.”

    ^^About the storing of “food” for when it molts, probably why your crab was just interested in water.

    I’d share the link but I don’t know if it is against the rules or not.


    It does sound like he needed some more water. The water stored in the water sac is how the crab grows while the exo is still soft. It will use that water to make itself swell up before the exo hardens.    I also have some crabs that just seem to spend most of their time buried.
