this post to the crab forum explains it:
rupert, my most favoritist and oldest owned hermit crab is streaking again.
he first started streaking after a surprise molt when he was still pink and soft, but he got back in his shell and everything was fine.
now he's hardened and has emerged from the sand (he stays buried almost all of the time) nakie, but is crawling around and stuff just fine. i don't want to leave him in the main tank, because before he took a new shell relatively quickly and i think it might cause more harm than good to iso him at this point. (also he's under my second level where i can't reach him)
he's been naked for about 10 mins.
no one seems to be agressive to him except lentil. rupert tried to enter the coconut hut and lentil tried to attack him.
gah! what should i do??
edit: okay, so he climbed in the coconut hut and lentil tried to attack him so i moved the hut so he was the only one in there and then arly (the smallest crab!) unburied and started going after him o_O
i managed to use the coconut hut as a sheild long enough for him to claim a new shell of his own. so now he's in a shell again. i have no idea why he's dropping his shell. i'm beginning to think it's so he can fit in the tunnels he's made under the sand.
i'm so frustrated!!!! i have no idea what to do. i moved him to the second level with all the food and water in case he needs some strength since he just molted a week ago, and because currently there are no other crabs up there. i also put two shells bigger than the one he hurriedly crammed into incase his squishy bum is being cramped.
should i iso? he seems healthy other than the streaking. alert antennae, his eyes are up, he's moving quickly.
:\ i really want him to be okay, he is my favorite crab.
that's his squishy bum, he's caked in sand because he was buried.
i feel so fucking awful. i know there's really nothing more that i can do, and i hate being so helpless. it makes me feel like a bad surrogate crab mother.
