If you don't give hermit crabs plenty of space and food they become cannibalistic. In fact they may eat the babies just because they are smaller and in their 'territory'. They are however social creatures, but i'd keep the babies separate from your others till they are larger.
Hi i have 1 red legger 4 green leggers and i just bought 6 baby blue leggers and i was wondering if they will all get along and if babys will be ok
