I've been told by many many breeders around here(trust me I have had my concerns with cohabitation) and the answer every time has been "absolutely no issue as long as you aren't feeding them together."
So I might house them together, and maybe not... They seem to house well together, they ball up in the same hide, and don't even seem curious of each other.
Anyhow here is a picture or two of my female:
