I have two medium PPs that have been consistently burying themselves for the last few weeks. They do not have a cloudy pre molt appearance. Does this necessarily mean that they are not ready to molt? Should I move them to an ISO tank just in case? When our first small crab molted it was a complete surprise and he came through it just fine. When we found him, we carefully relocated him to the ISO along with his exoskeleton. When he ate that, and appeared active again we put him back....now he stays on the surface all the time. It was weird because the other smaller crab was also burying himself, but did not molt as far as we know...so two crabs exhibited similar behavior...one molted, one didn't...now the two mediums are behaving the same way....I'm confused....Will I screw up their cycle if I dig them up and check on them? I just don't want to lose a crab and I'm so confused as to the correct course of action. I dug up a med. this evening and he reburied within two minutes! Does it hurt them to go without food during the molting process? A little guidance will be greatly appreciated!
