I'm going to assume that your common name refers to some species of Centruroides -- most likely C.vittatus or C.exilicauda. You might do well by checking this out, as a different species will obviously act differently.
Anyhow, Centruroides sp. generally do rather well in communal setups, provided they are well fed. That being said, there are no guarantees when dealing with communal species.
It may be a good idea to look through some of
these threads.
