I have a med/large crab named Shorty that is apparently getting ready to molt again. He's had the food/water storage bubble for weeks, and has been very lethargic. (He's normally very active). My question is, for how long will a crab show pre-molt symptoms before he actually starts digging? He hasn't hardly moved in weeks. I haven't seen him eat or drink for weeks, either! (and I'm up late into the night sometimes). When I spritz the tank, all the crabs become active, and sometimes he'll then change position, but then he'll just sit in the same spot for days. Literally! I'm worried about him. Tonight I coaxed him out from under the hut and he did walk around the tank a bit. He walked right through the food dish, and up to both water dishes, but never took a bit of food or a drop of water. I've even tried slipping a slice of apple (his favorite food) in front of him when he's under the hut, but he ignores it or turns his back to it. Is this normal? He didn't act like this for his first molt. Thanks! Donna M.
