Hello! I've had my hermit crab for almost a year now, and he always burries himself under a toy log I got him, I can't tell if or if he has molted, what are the signs? Also I just tried a new diet for him because he is so lethargic, do you have any ideas of why he is so inactive and what I can do to help? (I let him run around on the floor for a bit everyday, but in his tank he is always burried) thank you so much!! Your blog is so helpful
