My smithi mantis was eating awesome and looked nice and healthy he then started to build a blockade in his cave as many mantis shrimp do to molt I thought he was dead on the end of week 3 so I tried to take it apart and they were wedged in there good! I opened a small crack and stuck the dull end of the feeding skewer in and he punched it and looked at me through the crack so he is still alive but why has he not molted/gone out of his cave yet?
