i have two coenobita clypeatus. in other words, two Purple Pincher Hermit Crabs. the boy is the red variety and named Rhubarb, and girl is the normal colors of PP and named Calico, she's a bit larger than the boy too.

i've had them about 3 years now, they get bigger every few months! hehe, they are my 'fat babys'.
they have a diet of natural foods much like i eat. things like fresh veggies, fruit, nuts, grains, seeds, cheese, eggshells (for calcium), oak bark & dry oak leaves (for tanins), and sometimes a nice drop of olive oil. since they have a stomach the size of a match head, they are very, very low maintenance pets.

and sweet personalities too! the girl likes to cuddle on my shoulder and sleep. she makes very soft bubble-pop sounds at me when she's content. the boy just likes all the attention he can get, lol.
