my little brother just got one for his birthday - he's pretty cute.. rob (my brother - is 9) dropped him on the first day or so - so we called him lazarus.
We were told at the pet store they're solitary animals, he's in a fish tank with sand, some heat, water, a larger shell to grow into, sultanas and oats.
Although heard recently they're actually quite social - but that's always the way - when do you ever get two people who give you the same answer huh?
