Crabs

We have hermit crabs now. My FIL brought them back from Florida, and bought us a 10 gallon fishtank to put them in. Seems like overkill to me, but there are 8 of them (crabs, that is), so i guess they do need room to run. The kids LOVE the little critters, they change shells all the time, crawl around, dig, and climb on the rocks and sticks and stuff in there. We're still trying to figure out the temperature and humidity thing, but they seem happy and we have no mold growing *yet* but we're working on getting some kind of heater, because our house is really cold, and it seems inhumane to keep the lights on in the tank 24/7 like we are.
