So Long Dear Friends

I decided to take the three new hermit crabs back to the pet store today. They didn't seem to be doing very well in Q's class...probably due to the low humidity level and less than ideal living enviornment. I had 15 days to decide whether or not they were returning home and I didn't want the poor guys to die of a slow painful death....can't you tell I've been reading up on my hermit crab literature?! I think the class wants to now pursue chinese hamsters. Ever heard of these? Here's the important question...are they high maintenence?
