Hi, Daisy's Mom,
I know that you posted this a while ago, but I just wanted to say that you brought back some fond memories from a long time ago. (well, not THAT long ago!)
When I was in the third or fourth grade, our Science Class mascots were two little hermit crabs named Peaches and Herb. I remember thinking that they were pretty cool pets and we got to take turns feeding them and bringing them home for long weekends. I had totally forgotten about them until I read your post.
