Hello My name is Jennifer and I am a new crab mommy along with my two daughters, (they are 7 and 3) I have been looking all over the internet for hermit crab information and care, I have found a few but this one l like because we can get answers to all of our questions. About our crabs. It was my 3 yr old who received the crabs for her birthday in September from my husbands aunt. We had no idea they were getting the crabs. I was so grossed out by them I would run when ever my husband opened their tank. My 3yr old was braver then I was. She is a big spongebob fan so all of our crabs are named after the characters and our crabitat is bikinibottom. Anyway, over the first couple of weeks they began to grow on me and I would watch them with her in her room. We had them in one of those small plastic containers with a half inch of sand and a small water bowl with a sponge, basicly not room to move. I started thinking I really need to learn what they need. I felt bad for them. Long story short, they are now in an old 72 gallon reptile tank (found it on ebay-great deal) with tons of rocks, hills ect.
