Hi I am a new owner of a hermit crab of which just came into my life about a half hour ago. I went to bed and heard something outside and when I went to look there was a hermit crab on my porch! It is very large - about 1/2 the size of a fist and by the shell I would say it was at one time someones pet. I know nothing about this type of animal except for what I have found out in the past few minutes. Any words of advice?????? 

Thanks,

Dawn
