I would say no to having two Jax in one cage, unless you have an absolutely enormous enclosure. (we're talking greenhouse size) Jaxx are VERY territorial and generally dont thrive if they have any contact with each other, in my experience.
Someone will probably come along and correct me though, and if they do, they do, no biggie.
There arent any unusual jaxx morphs, theyre basically green for males and olive for females. The speices hasnt really been worked with that much in captivity to my knowledge. But, why would you want weird morphs when theyre beautiful and unusual enough as it is?
Also, what specifically made you want a Jaxx? Theyre not ideal first chams, they have some pretty sensitive requirements and they dont take to handling well at all. I'm not lecturing you, im just curious. If you want a cham that will stand up to a little handling, get a Panther or a Veil. If you want a cham that just looks really cool and is happy in his cage being looked at, then go ahead and get a Jaxx.
Hope that helps a little, just my $.02.
