There are communal scorpions but emperors aren’t. Babies usually hangout on mom’s back for a little bit. Once they crawl off mom’s duty is done and she’ll eat them if kept together. The babies can be kept together for a short time so long as you feed them pretty well. But even then you might lose a few. When we used to do this we weren’t interested in making money so if we lost a few to the thunderdome it was no big deal.
