I went to Petsmart last night, and against my better judgement, looked at the hermies, wish I didn't now! They were sitting in two large aquariums, screen lids, completley dry and looks like they have wood chips or mulch for substrate. The employess were all hanging out, chatting and playing with a lizard. Finally one came over and asked if they could help me. I siad yes, could you please give those crabs some water and mist their tank? He said, they don;t need water or misting!! I went on to explain about thier gill function and how they needed to be in a warm and humid environment, to which he replied I must not know what I am talking about because Petsmart has NEVER, EVER had a hermit crab die!!!!!!! I am calling the store manager today, she does not get into the store till late afternoon is what I was told. Maybe it would be better if hermit crabs were not sold anywhere, too many are being killed or made to suffer ??
