Aslong as they are both sexually mature, they both have seperate hides I don't see any problem. Just for 2 p.imps the space you need isn't really that much more than the space for 1. Just keep them well fed to avoid cannabilisation and keep an eye on them after they mate as I've heard horror stories of the female eating the male afterwards. In captivity the male doesn't really have anywhere to hide!In most occurrences of combining a male and a female imp. scorpion that they mate? Also, how big would the living quarters have to be for them to live comfortably?
