I bought two new babies the other day. The final straw was the other day hotball looked so lonely. I have a cluster of empty shells in the tank (4 shells) and he spent all day over there moving them around, sleeping next to them. Either he was wishing for a friend or is planning on changing shells. Where I have no experience with that, I don't know how to tell if they are thinking about switching shells. So I jsut assumed he was really really lonely. The day we got them I bathed all three. (I read on some post you should do that so they all smell the same) Anyway, when I put them in the tank, one went to one corner the other ran to the other corner and my baby hotball went from one crab to the other a couple times and finally went to sleep next to one of them. The two new crabs have buried themselves. I cannot see them at all. It has been almsot 3 days now, so my poor little friend is alone again. So now what, just wait? or shoudl I dig them up and make sure they are fine?? I actually have no idea where they are they are so hidden there is no sign. Can they breathe??
