HCA: Hermit Crab Association

I have three Ecuadorians and one PP, and recently read that my one PP could get lonely even with the others in the tank because they are of different species. Is this true? I could get another pp if needed, but my tank is a bit small for five crabs.

If you feel that your tank can't handle another crab then I would put off getting another (unless you want a second tank).

Could your PP get lonely? Maybe, but there are also of cases of lone PPs living for well over a decade.
