To start off, I owned the phyllocrania paradoxa twice. I've had 4 of them last year and bought 6 again last week. I keep them because I love their camouflage and shapes if their bodies. I'm planning on owning other species later on but haven't figured out which ones yet. I may be looking for a more active species since ghosts mostly don't move around all that much. I've heard that boxer mantids are very cool. Also, I would definately recommend phyllocrania paradoxa, they are an easy to keep mantis, don't need that big of an enclosure and you can keep multiple of them together, the only downside is having to deal with raising maggots since they only eat flies.
