Newbie ghost mantis help

[mmcguffi]

Hey guys I just picked up one female and one male ghost mantises (L3/L4?) and I set up a ~1.5 gal terrarium with live plants. Can I house them together? I've read conflicting reports on canabalism. Will I be alright housing them together?

I raise mine communally. However, there is always a risk. I probably wouldn't keep mine together if I only had one male and one female.
