african giant communal housing

hi all! i recently moved my african giant millipede to a 70 gal and was looking to get 1 or 2 more captive bred from us invertebrate llc. however, i acquired her through a reptile con and im not sure if shes wild caught, but im 99% sure she probably is since im in the states and theyre hard to come by not imported. i was wondering if theres anything i need to be worried about by bringing these captive bred guys into the same tank as my big girl such as sickness, faulty breeding, etc?
